Believe it or not, I actually have that book here in the house. I bought it a LONG time ago.
When I lived in Orlando, I was wagering $1100 a week, every week, on Jai-Alai. At the time you could "advance wager" up to two days in advance of the actual game so every other day the wife and I would drive up and make the advance wagers.
I was seriously into computers and this was a time when almost everyone used pencil and paper to track what they could. I wrote several very nice routines on those old computers and had DAILY printouts of which games and players to wager on.
When I left the area, computers still hadn't caught up with Jai-Alai and I had some very interesting offers to purchase my years of data. I eventually gave it away to a very deserving older individual that I had struck up a great relationship with on Jai-Alai and all things worldly.
Now, everyone and their brother has the data basically handed to them with each program for a dollar!! What separated my data from the current data was the depth and percentages that I carried over time.
Yes, I did show a nice profit year after year in the pari-mutuel arena, but it was literally a daily grind. I loved the game so much I actually learned to play it from the pros and played in the open public leagues that they had there. Jai-Alai is a beautiful game but I can only see it now when I head over to Miami or Dania to visit friends. They closed the Tampa fronton about two weeks after I moved to the west coast of Florida.
That book that you mentioned had some good data in it but it is now terribly dated. It did give me some great programming ideas at the time though.
