Is there anything New?
I think the majority of missing pieces out there for handicapping data involve the actual betting. There's tons and tons of data on PICKING contenders but not all that much on BETTING contenders.
If I could magically tell you the winner of a single race with 100% sureness and give you $100, how do you bet it?
There's win, you can top an exacta or tri to all, you can double to all on either side, etc. I wonder how many handicappers actually possess the skill (or will) to actually analyze what the right decision is given this scenario.
I couldn't even count the number of times I've heard people comment (especially myself included) that they had the horse...but they just didn't bet it right.
