I was going on a quote by quote basis for context but it is getting a bit messy!
While we both want the opportunity to witness greatness, it would appear that we differ on how that greatness manifests. Quevega winning the same restricted race over and over again is an endorsement of Willie Mullins' skills. It is also an achievement of consistency but not necessarily an achievement of outstanding merit. Risk of Thunder and Credit Call both achieved their landmark wins in restricted events (La Touche Cup and Adam Scott Memorial Cup respectively) with Timeform ratings of 111. Conversely, Hurricane Fly's achievement of winning the Irish Champion Hurdle five times is more a component than the sum of his greatness. Feel free to put Quevega on the same pedestal as Dawn Run and Annie Power. That is your want and nobody can take that from you. But she can only be the equal of those actual champions by dint of sentimentality. Furthermore, would you deny that Quevega's absences from the Stayers' Hurdles deprived those races a degree of quality?
To clarify, I am ambivalent about the impact intermediate novice races have on their shorter and longer counterparts - a criticism levied in the earlier posts by others. I am not ambivalent about their existence. I like novice races. I think novice races are good. I believe we have may have found some common ground here.
As much as I respect your inside track, it occurs in a timeline where the Ryanair, the Mares' Hurdle and the hypothetical Intermediate Hurdle do not exist. If Quevega was in her pomp during the early 2000s, there would have been no chance of her running in the Mares' Hurdle. A few of the 129 horses who have contested the Ryanair since it was given Grade One status might have gone for the Cathcart had they qualified but none of them would have gone for the Ryanair. Under the contemporary conditions, you may have understood or even have been explicitly told the plans of the trainers and owners. However, not even the connections themselves can categorically tell you about hypothetical decisions they would have made in an alternate timeline. Particularly as they can often leave decisions to race selection weeks, days or even hours before the festival itself.
I am not suggesting that every single top class two miler and stayer can run to their best at twenty furlongs. I have used examples such as Sanctuaire, Young Snugfit, Native River and Bonanza Boy to show that some horses have ranges that fall either side twenty furlongs. Sanctuaire and Young Snugfit may have been unbeatable in fourteen furlong chases while Native River and Bonanza Boy could have been imperious in a weight for age Grade One Eider Chase. Nevertheless, the aforementioned are still a minority among the best jumps horses since most will have a range which encompasses two and half miles. My theory is that the more measured pace over jumps than on the flat means that the difference a furlong or two makes to flat horses translates to roughly twice that over jumps. As most flat horses have an optimum distance range that encompasses at least two furlongs, so then will most jumps horses have one that encompasses at least four. Sometimes this range is greater even than a mile with examples such as Flyingbolt, Kauto Star, Desert Orchid and Dawn Run. But a perusal of the many many horses/examples mentioned in this thread will show that the best at two and three provide the best at two and a half. It is not a coincidence that the so-called twenty furlong specialists are almost always inferior to the two and three mile horses even when they meet at the specialist intermediate distance.
My statement was that if a horse can place in a Champion Hurdle or a Stayers, it has a right to be considered at least a two or three miler respectively. I did not state that they would be able to produce the same in an intermediate championship race although this has been shown to be true much more often than not. What I did state is that the best intermediate performances are almost always made by two and three milers which I demonstrated with the evidence provided in that break down. Using your Rock On Ruby example, is the argument that he was a sixteen furlong horse who was way below his best at twenty furlongs? He absolutely stayed twenty-one furlongs since he ran all the way to the line on each of the four occasions he tried the trip at Cheltenham (yes he was nabbed by First Lieutenant but he still pulled clear of the rest). His Aintree efforts were no more than a few lengths off his Champion Hurdle runs and were as good as anything else he achieved at two miles. Those few lengths are more sensibly explained by the fact that Aintree was either an afterthought (as was Punchestown when Hurricane Fly extended the gap between the two in 2013) or followed an interrupted campaign, than the idea that he was, say, seven pounds worse off for the three and a half furlongs sans the Cheltenham hill. Comparing him to The New One doesn't help either since not only did The New One beat Rock On Ruby ten lengths over two miles at Kempton but Rock On Ruby ran in the Relkeel to avoid meeting The New One in the Bula on the same card. All Rock On Ruby v The New One example shows is that performances within that range are interchangeable, supporting my argument without anything resembling a struggle. If we are to assume that The New One contested the Intermediate Hurdle in 2014, 2015 and 2016, then first of all, you have deprived the Champion Hurdle of a horse who started at 10/3, 10/3 and 7/2 - far from a non-hoper. We also have to believe that he would have been able to beat Jezki, Hurricane Fly, Faugheen, Arctic Fire, Annie Power, Nichols Canyon and Quevega in this intermediate race. If you believe that The New One would win the intermediate race against that field three times then you also believe that he was the greatest hurdler of the twenty-first century. If you do not then he was not even the best at the trip in his time. This shows that your Intermediate Hurdle race will either produce unworthy champions or decimate the Champion and Stayers'.
As for the RPR argument being irrelevant, the RPR argument is an actual demonstration of the best performances at that distance this century. Whether they range from 165-175 or 175-190 is immaterial. The horses I posted were literally the best at twenty furlongs over hurdles this century. There were none better. I also posted earlier the most successful horses in twenty furlong events jumps and hurdles over the past forty years. I have no idea where else one could possibly look for the best twenty furlong horses. Yet neither you or anybody else has named a horse who is/was both;-
a) Champion standard - would beat every other horse in training over twenty furlongs
and
b) A twenty furlong specialist - whose form would dip to the point it would no longer be competitive at the best two or three mile races.
If there are horses who regularly satisfy this simple criteria then there is a justification calling two and a half miles a stand-alone championship distance. There are horses that can beat anything at two miles without necessarily being able to beat the best at three. There are three mile champions who might not have the pace for two. There are great horses who could mix it with the best at two and three and exceptional talents who were champions at any distance. But for all the names spilled in this thread, few if any that honestly can be called specialist two and a half mile champions.
I am open to the same being found to the extent that I have compiled a list of the 422 horses who have placed in the first three in all weight for age renewals Ascot Chase, Ascot Hurdle, Hatton's Grace, Punchestown Chase, Aintree Hurdle and Melling Chase since the 1983/84 season. All of them. Every single one. I have even thrown in placed horses from the Black and White as well as the Cleeve Hurdle from when it was a twenty furlong race (which was downgraded from Grade One, presumably because Kates Charm and Classified were not championship standard).
I will not post all 422 horses in this post so this list, which I can not attach at a decent resolution, can be found
here.
If there is any such thing as a specialist twenty furlong champion from the past thirty six years then it will be among that heaving mass.
If a horse is shorter than 10/1 then it is not a non-hoper but a live contender. The shorter, the livelier. (If you do not like using odds as an analogy then percentages work just as well). If there are horses that are competing in the Ryanair who would have stood a 10/1 shot's chance or better in either the Champion Chase or Gold Cup then that means the Ryanair, simply by existing, has deprived those races of a contender. It can not be said for certain what would or would not have won a race because there are no thousand-to-one-on shots running at the festival. The best we can do is use odds in order to roughly gauge the damage the Ryanair has done to the Champion Chase and Gold Cup. Since you are unwilling to name horses who would have stood absolutely no chance in the big races, despite the burden of proof lying on yourself, I will name the horses likely to have had started at 10/1 or less in that year's bigger races.
2008
Old Vic - GC - staying on when second the previous year
Mossbank - GC - ran away with Munster National, staying on when second to Denman in the Lexus, sole Gigginstown runner
2009
Imperial Commander - GC - won the Gold Cup the following year - did not need to improve much from eight to nine
Voy Por Ustedes - CC - dual winner and runner up in 2008
Tidal Bay - CC - won 2008 Arkle by 13 lengths, second in Tingle Creek. Also GC - stayed the trip and rated higher than 10/1 shot Barbers Shop
2010
Tranquil Sea - CC - 121 in Graded 2m chases that season, CC had open market outside of Master Minded.
Voy Por Ustedes - CC - see above
Albertas Run and Barbers Shop - GC - larger than 10/1 but both had better prospects than the 12/1 Tricky Trickster
2011
Albertas Run - GC - dual festival winner with better chances than 9/1 shots Midnight Chase and Kempes
Kalahari King - CC - Arkle 2nd, Champion Chase 3rd, comes to life at festival
2012
Riverside Theatre - CC or GC - speedy novice who was runner up in a King George, impressive return in the Ascot Chase after a year off the track, would have been a live contender for either race in the pre-Ryanair days
Albertas Run - GC - getting on a bit but that year's GC was not the strongest - even Medermit would have been given a place chance
Somersby - CC - won Clarence House last time beating CC winner Finian's Rainbow. Highest rated UK horse in field - ended up finishing second in the 2014 and 2015 renewals in any case
Noble Prince - CC - 1222 in graded 2m chases that season
2013
Cue Card - CC or GC - Arkle runner up who won the Haldon Gold Cup by 26 lengths - would have been joint second fav with Sizing Europe in a one horse market, seven year old Cue Card was possibly too young for a Gold Cup but he would not have been lightly dismissed
First Lieutenant - GC - was only in the Ryanair because Gigginstown had Sir Des Champs in the Gold Cup. Would have been right near the top of the market
2014
Dynaste - GC - second in Lancashire Chase, injured when King George favourite, was favourite to beat 1¾l GC fourth Silviniaco Conti next time at Aintree
Hidden Cyclone - CC - coming in off two consecutive seconds in two mile Grade Ones, fell when favourite for Punchestown Champion Chase next time.
Al Ferof - CC or GC - Supreme Novices winner would have been better fancied in a Sprinter Sacre free field than 7/2 shot Captain Conan, wouldn't be longer than 10/1 shot Tirolo D'Alene in the Gold Cup either.
Boston Bob - GC - another case of connections splitting horses - held every chance when falling in the RSA - ended up winning the Punchestown Gold Cup the next month
Benefficient - CC - Won Dial-a-Bet chase last time
2015
Uxizandre - CC - winner of Shloer Chase - probably would have been longer odds due to his being out of form which is a reflection of the quality of this race
Don Cossack - GC - won the next season's Gold Cup but would still have been vying for favouritism even in the highly competitive 2015 edition
2016
Vautour - CC or GC - would have been strongly fancied for either
Valseur Lido - GC - looked all over the winner in the Irish Gold Cup
Road To Riches - GC - third in that very race the previous year
2017
Un Des Sceaux - CC - already beat the winner twice, no reason to suspect he why he would not have made it three
Empire Of Dirt - GC - easy winner of Troytown and keeping on when narrowly beaten by Sizing John in Irish Gold Cup
2018
Un Des Sceaux - CC - see above
Cue Card - GC - would have been in Gold Cup but for Native River, would not have been an outsider
2019
Frodon - GC - won Cotswold Chase,
Road To Respect - GC - fourth in 2018, three wins and four places over three miles in Grade One company
Monalee - GC - keeping on second in both Spa and RSA novices'
Un De Sceaux - CC - see above
Footpad - CC - won four Grade One novices at two miles - including Arkle - by combined forty-two lengths
If you say that there is just one possible winner out of those thirty-eight then I find your sense of humour quirky but amusing. Even if there just a few winners then that is still carnage. Statistically, it is highly improbable that there are not numerous winners and placed horses among that selected group - let alone the remaining ninety-one that I ignored. Even if by astronomical happenstance not a single one of those horses could get close to winning, the strength in depth of the Champion Chase and the Gold Cup has still been compromised. The 2016 Gold Cup being one notable example of several.
In responding to Granger I already addressed Archie's stats (and provided more thorough and accurate numbers) which does nothing to counter the argument that the quality of the Champion Chase and the Gold Cup have been affected.
Increased field sizes + diverted quality runners = diluted fields in CC and GC
Decreased field sizes + diverted quality runners = diminished fields in CC and GC
Field sizes are not a useful metric when the constant diversion of quality runners is the issue at hand.
Now you will need to make clear to me exactly what evidence you are looking for and which claims I have not substantiated because I have not been filling this thread with shopping lists or gluten free recipes. Into this thread I have thrown copious amounts of names and statistics relevant to my assertions. Deliberately comprehensive and exhaustive so as to mitigate against any accusations of cherry picking. Every theory and observation has been based on empirical evidence provided and repeated numerous times in numerous forms. If I have made a point without evidence, feel completely free to expose any empty assertion.
On the other hand, I have not been offered a single twenty furlong champion, a refutation of the chances of the aforementioned thirty-eight or a single explanation as to why there is so much overlap in the Champion Chase and Ryanair markets.
