I agree with you and when I said the same a few weeks back I was told I was trolling; clearly not.
.
As things stand, I would strongly fancy the following to finish above him..
Master Minded......Agreed
Big Zeb.........Agreed
Captain Cee Bee......See last year's Arkle
Woolcombe Folly......Maybe
French Opera.....:lol:
Somersby......See Captain CB
Mad Max........See Somersby
Golden Silver......LoL. Appalling record at Chelts.
Tataniano (if the ground 'good' enough for him):lol::lol: The two mile version of What a Friend.
Okay, one more time...
Somersby and Mad Max have posted better performances subsequent to the Arkle than SE did in that race, and are (certainly in the case of the former) better horses over 2m.
Captain Cee Bee is for me a better horse, but one with more to come as opposed to the form in the book. Plus, his Arkle run can be written off as he broke a blood vessel. Not that I think he has to rely on this, but on a line through Osana, he is better than SE.
Tataniano - his Aintree win was comfortably the best 2m Novice run of last season. He can be forgiven his opening run this season and hasn't run since. He would be able to beat SE without factoring in any of the likely improvement still to come.
Somersby 7/2
Woolcombe Folly 4/1
Golden Silver 4/1
Sizing Europe 5/1
Captain Cee Bee 6/1
Tataniano 12/1
French Opera 20/1
Scotsirish 20/1
Gauvain 20/1
Mad Max 33/1
Regardless of the fact I view the race differently to you both, the one thing we can all look forward to is the most interesting QMCC since Moscow Flyer's.
When horse win by wide margins, I think you are better served knocking a few points off their ratings when looking for a guide to future performances.
I don't have a precise formula to propose, but when a horse wins by a jumps race on testing ground by 20 lengths I apply the one-length-per-pound formula for say the first ten lengths, but change it to perhaps two lengths per pound for lengths 11 to 20. In this way I would put a 20 length winning margin as being roughly one stone superior rather the 20lbs usually allotted in standard ratings.
I get what you mean... it usually does pay to treat wide margin victories with some caution. I wouldn't be too eager to quantify that caution though.
