Only West Coast tracks post $1 exacta payoffs; the rest post $2 payoffs;
All tracks report Daily Double payoffs as $2 bets;
SA/GP/TAM report pick three payoffs as $1 bets; AQU reports $2 payoff info;
SA/GP reports pick 4 payoffs for $0.50 bets;Tampa Bay reports pick 4 payoffs for $1.00 and AQU reports for $2 payouts.

I used the Brisnet Chart Archives for the information in the study.

So if you are doing any workouts based on horizontal play, please note you need to make adjustments for some of the information reported depending upon which tracks you are studying
