Make of that what you will, although, at a glance, it seems to disprove the general basis of the theory, unless, of course, all of these achievements were made in slowly run races, which would seem a trifle improbable.
As you say, it is only a first glance, and such snapshots can mislead people and cause them to over look detail etc.
It's probably not unreasonable to assume that the horses listed might be regarded as being at the apex of their division? They have afterall run a first 3 finish in their grade 1 championship event (although quite a few will record higher RPR's in different races).
I think in fairness to your supposition, it's probably unreasonable to expect them all to be able to replicate their stayers hurdles performances when sent over fences, as just because they reached the pinnacle in one discipline, we'd be cutting them little slack in expecting them to faultlessly do same in another. They were however still theoretically, at a peak level of elite performance, and there would therefore be grounds to believe that they should be capable of setting a similarly high standard, if not eclipsing always it?
Contrary to your assertion, I'd suggest that the evidence weighs more in favour of the original hypothesis though.
Iris's Gift
RPR of 176 and winner of a stayers hurdle
When sent over fences the horse managed a rating no better than 155 in a Novice Chase at Cheltenham. The horse was miraculously 21Ibs better of hurdles, and badly found out over fences.
Crystal D'ainay
Finished 3rd in the stayers and earned a rating of 162 over hurdles. You might argue he hasn't raced over fences enough times to form a meaningful opinion? I'm sure you'd have good grounds to do so, but the best RPR I can find for him over fences is 135 in an Exeter Handicap. He's 27Ibs inferior at present, and offers no real encouragment to think he's going to bridge this anytime soon.
It Takes Time
This is one of the more interesting ones as his 3rd allied with his staying hurdles career gave him a top RPR of 163. The best Chase rating I can find for him is 161. So at face value you'd say he's replicated his staying hurdles form? Well perhaps not. If you dig deeper you'll realise that all his winning chase form (and highest RPR's) are at 2.5 miles.
In many respects he has a similar profile to MWDS in this respect. For such time as he was able to run 3 miles over hurdles, the lack of pace (or some other explanation) might have disguised his limitations. When he was put into the more competitive discipline and faster races assoicated with fences, his win ratio suffers quite noticably. Although he's also got staying form in marathon chases just to confuse the issue.
24F +
Hurdles = 4 wins, 3 places 3 unplaced - 4 wins in 10
Chases = 0 wins, 7 places, 7 unplaced - 0 wins in 14
On balance I'd conceed his chases were more competitive (but isn't that just confirming the tenet of my argument?) and there's some respectable efforts in his form, but still no wins at a staying distance.
Bacchanal
Won a stayers hurdle and earned a top RPR of 168
Won a Aon, Feltham, 3rd in King George and 12th in a Gold Cup for a top rating of 168. He remains one of only two horses from the list I think truly re-produced the same level of form (there's one other I'm uncertain about). Bacchanal's stats are remarkbaly similar over both obstacles, even though he reached the pinnacle of staying hrudles, he never really ever thretend to do so over fences
Behrajan
Is the other, and I think you could probably make the argument to suggets he was fractionally better over fences? In any event his top RPR of 167 over hurdles is I believe, legitimately (though marginally) eclipsed by his top chase RPR of 168
Le Coudrey
A lot of his early form was confined to reasonably rich hurdles races in France where no RPR's are recorded making it a bit hazardous. He only completed one run a 3 miles over hurdles and earned 173 for his effort when finishing second to Anzum in the Stayers. Even so, despite wining some grade 1 novice chases, and distinguishing himself in the Irish Henessey and Ericsson I can't find a chase RPR within 10Ibs of the one he put up on his only completed 3 mile hurdle, so he'd be another who achieved a higher level over hurdles than he managed over fences.
Paddys Return
This would be the third horse to join Iris's Gift and Crystal D'Ainay as one that was badly exposed when asked to tackle the more competitive assignment. His top RPR over staying hurdles was 171 put up in the Long Walk, where as his best chase performance was some 37Ibs lower. Indeed, so far as I can establish, 12 of his 25 hurdles ratings, were better than anyone of his 20 chase ratings such was the disparity between the two divisions.
Cyborgo
I think this one is inconclusive (alluded to earlier) Strictly speaking his best chase RPR of 165, narrowly beats his best hurdles rating of 164, so at face value, he'd be similar to Behrajan. But there's something weird about the 165. It's a massive 9Ibs clear of anything he'd ever done previously, or ever did again. The rating appears to have come from nowhere and stands out like a sore thumb as being potentially erroneous, or as evidence to the idea that every dog does indeed have its day. He ran 14 times of hurdles, and 12 over fences, 4 of his best 5 performances came over timber, the 165 really does seem to come from nowhere.
I'd say you've got 3 horses therefore who were demonstrably nowhere near the same level of performance once they were asked to step up to staying chases, and 3 who were able to match their form (I'll add Dorans Pride to the list, as I'd overloked him originally). Two others probably reached a higher standard over staying hurdles than they did fences, but wouldn't fit into the category of being embarassed, where as another is just inconclusive.
Now remembering of course that these are supposed to be the pick of the staying hurdles crop, I'm not sure that I would describe a figure of less than 50% as being supportive to the idea that they transfer their form. I reckon its nearer to 25% which although it's a matter of opinion, I'd have thought was below reasonable expectation?
