Interesting reading so far.

But the way I see it, everyone has a "system" wanted to be developed.
So there are many "systems" and many ideas,and If I can relate in contrast to a poker game, there are 2 ways I know how to deal a deck, as an "object".
1 "object" deck of cards is with 52 cards ( Full Deck)
2 "object" deck of cards is 32 cards ( 7's up to Ace)
But both method of play can still have a full house on Aces and Queens for example.
It's how one play's the game.

So what has this got to do with a horse race program ?
It's relatively the same in principle.
1 wants to use form
2 wants markets and/or form.

At the end of the day it has to come down to a factor when selections are obtained either from form, then bet according to price available ?


Both require data feed. ( form data feed and market price data feed )
The computerable data feed, where is it's most stable "raw source" going to come from to compute a method of selections, and be commonly agreed upon ?

And why ?
