This is very good data; it goes much deeper than HA, of course. I have several programs I wrote that crank out ev, SD, skew, etc. Actually, the SD for 11 $6 place bets would be $21.47. The SD for a single place 6 bet is 1.0788 times the amount of the bet. The SD increases with the square root of the number of bets, so sqrt(11) * 1.0788 = 3.578 * $6 = $21.47. BTW, the Configure/Advantage tab in WinCraps shows the ev and SD per roll and per decision for every bet on the table, just another of the great features it provides. It's the best $20 you will spend, probably.
