I'll be crunching some numbers later in the week and will get back to you with my findings.
Finding the right going allowance is always the key to accurate time ratings so with the caveat that I might not have the GA correct, this is what I'm coming up with:
The consensus that the Guineas and the closing C&D 3yo handicap are the most true-run races on the card is what my findings agree with. It's a matter of how good is the handicap.
I've agreed with the handicapper and gone a touch high with it. The GA allowance extrapolated from the form, once applied to the Guineas, brings Galileo Gold out on 'only' 108. I see that Topspeed has 109, similar to some recent winners but a long way behind others from not long ago. That, too, probably mirrors my own findings (but I can't be arsed to go up the loft to check right now) but it also means I'm not going to let myself get carried away with the form. And that is simply because a time rating like that becomes meaningless to me in the context of that race. Had he come out on a par with something like Makfi or Cockney Rebel - genuinely fast races - I might be seeing it differently. I just think Galileo Gold has won a moderate renewal. The exposed Ribchester in third dents any confidence in this being a hot race. The fourth and fifth, the latter a 100/1 shot, came into it on marks of 107 and 90 and the sixth, Zonderland, was off 106 but on lines with Ribchester has improved to 108.
On those form lines, I have Galileo Gold on 121, about on a par with Footstepsinthesand, if memory serves.
I have the fillies some way slower. I don't think the conditions allow a direct comparison, eg Minding ran the same trip only 0.62s slower. I have her fully 14lbs slower on the clock.
We have to look at the form ratings more closely, therefore.
The average rating of those placed 2nd to 7th is 108. In the boys' race it is 107, being pegged down by Kentuckyconnection's 90. Take him out and replace him with the 8th and it rises to 111, or the 9th and it rounds down to the same 111.
If we award fifth-placed Nathra the average 108, it puts Minding on 122.
If we award fifth-placed Kentuckyconnection 111, it puts Galileo Gold on 123.
That's not how I normally do thing, by the way; I'm merely attempting to proffer a less subjective approach than "I think..."
I haven't yet finalised my figures for the fillies. I always find them harder to get accurate since they are generally less consistent than colts. But I reckon I'll settle on 121+p for Galileo Gold and 117+ for Minding via Fireglow (OR105, 40/1) and Mix And Mingle (OR100, 50/1) running to within a couple of pounds of their marks.
