What's Winning at Gulfstream So that means a top horse "8" and a top horse "3" are all included.
And THAT means you can easily break out the 3s from the 8s and all the others to see if there are SUBSETS that are more powerful.
You should have a good time with that.
I'm not sure I'm understanding "subsets". Are we looking at races where the best early speed number is 7-8, and then races where best early speed number is 5-6, and then races where best early speed number is 3-4 and we're doing this to see if 7-8 races produce more winnners (or more money) than 5-6 races?
