You've made the point, & I've disagreed with you, on a number of occasions, though not recently. According to the Tampa GM, in 2003 batch wagering accounted for $7.4 million in bets, & those making the bets received back $8 million, which is a very impressive 8% roi, which gets even more impressive when the rebate is added in. However, given the amount bet one presumes that someone who was able to hack into or otherwise cheat the system would do quite a bit better than that. I also doubt they would target the pk3 or pk4, since the obscenely confiscatory takeout on those bets at Tampa is 25.9%. The fact that a track which is imposing such a takeout is being heralded in some quarters as sticking up for the average bettor by closing down the rebate shops shows how crazy the debate over the issue has already become.
