With the Gosforth Cup, 5.25 Newcastle, at least we have a sprint worth spending time on.
From the Post forecast of 5/1 Navello, 6/1 Copper Knight, 7/1 Prince Of Zenda, 8/1 Thunder Moor, Ziggys Missile, 10/1 Bergerac, Burning Cash
I make the first numerical picture horses Navello (consistency total 8), Burning Cash (11), Copper Knight and Thunder Moor (both 14).
Following the 1988 Mackeson procedure, the three with the highest ability ratings from the four in the first numerical picture are Copper Knight (AR 198), Thunder Moor (183) and Navello (119), so Burning Cash (72) is jettisoned, but those in the field with the three highest lto class ratings are also now considered. These are Bergerac, Mattice, Ziggys Missile, Makanah and Burning Cash (all from class 387), Prince Of Zenda (255) and Navello and Thunder Moor (both 157).
Would VDW have added Burning Cash back in, having jettisioned him initially? No way of knowing so, playing safe, I do. So this gives six to add to the three: Copper Knight, Thunder Moor and Navello, now plus Bergerac, Mattice, Ziggys Missile, Makanah, Burning Cash and Prince Of Zenda, with two (like Pegwell Bay in the 1988 Mackeson), appearing in both sections, Thunder Moor and Navello.
The third numerical picture is, I assume, those within the nine that VDW would have regarded as form horses; being generous, all except Ziggys Missile and Makana. The question then is whether the third numerical picture is completed by ranking the seven in descending order of ability ratings, or before doing that, would VDW have jettisoned any he thought failed on "the other factors". Given his comments on Mackeson runner Jim Thorpe -"the distance is wrong and he requires much softer ground to perform well" - and that he made the lower ability-rated Pegwell Bay as the class/form horse over Jim Thorpe, I think he would.
Taking the seven alphabetically, on "the other factors":
Bergerac, Burning Cash and Mattice and have all won, or run well, over the trip, on the aw and on the course type, and weight seems no issue with them.
There are possible question marks in respect of the others:
Copper Knight. Has yet to run well on the aw (three tries so far)
Navello. Has never won nor gone really close on a power course like Newcastle, though maybe the run on 16/04/24 at Newmarket would provide enough re-assurance
Prince Of Zenda. First time over 5f,.
Thunder Moor. Like Navello, has yet to win or go close on a power course.
I am far from sure whether VDW would have eliminated any of the four on "the other factors" consideration, but sorting out the class/form horse depends on it.
The seven, in descending order of ability ratings, are:
Copper Night - 198
Thunder Moor - 183
Bergerac - 142
Navello - 119
Mattice - 106
Burning Cash - 72
Prince Of Zenda - 63
So, if VDW had not jettisoned any on "the other conditions" considerations, Copper Knight would have been the class/form horse. The highest ability rated horse with, as far as I can see, no "the other factors" question marks is Bergerac.
Assuming that whatever judgements VDW made on "the other condtions" considerations, there are thus three who might have been his class/form horse. The question then becomes does any of the three have the kind of form profile VDW indicated he backed.
Copper Knight. Going up in class on both penalty values and strength of field as per average ORs. Won lto as favourite, which is very much what VDW liked in class risers. However, his consistency total of 14 is higher than every class-rising selection VDW gave. So maybe both a consistent horse and a form horse, but not what VDW referred to as a horse with consistent form.
Thunder Moor. He is also up in class on both measures and came 3rd lto when 10th in the betting. The only comparable VDW example is Castle Warden, who VDW made clear was not a bet.
Bergerac. Down in class, having been 8th lto when 10th in the betting. Both well above those of any of VDW's class-dropping selections, which is a pity as he has just the right kind of key horse support of the form for which it seems VDW looked.
Overall conclusion. Whichever of the three VDW would have regarded as the class/form horse, I doubt he would have thought it was strong enough to back, ie it would fall into the usual (for VDW 80+%) category of a class/form horse left to run unbacked.
A final thought on the race. Copper Knight has (assuming my figures are correct) the highest ability rating in the field, in part due to his win on 18/08/21, a class 361. Each of his five wins since then has been within the range 103 to 179. Today's 258 would, if he won, be his best winning performance in nearly three years. How likely is that, bearing in mind he is now a 10yo?
My own approach to ability suggests not very likely at all, as illustrated by the attached chart.
