I understand play on line moves. Also I figured out about the second part of my original post - the smaller offshore books are not pari-mutual and therefore don't pay track
odds past 10-1 or whatever. I thought the smaller books were followibg as well and obviously if there is a big move they have to adjust to chase away the middlers (they call it arb around here???) But there are too many lines and they update too quickly - sometiimes 10 or 15 at a time, so it can't just be because they follow the bigger books and update them manually. It's got to be automated somehow - so somebody has to be providing the data for the update. Is it that Los Vegas Consultants group that sets Vegas lines? I heard a rumor that the smaller books pay ~$5K a month, but that's just a rumor. Maybe they just store le lines as a table in the database that holds the players action and a script runs every 30 seconds or so that acceses a remote database and updates the local one?
