The mistake in your later email also is not the fault of vpgenius. I suspect that your posting of 97.1756% was for a pay schedule that pays 250 coins for a straight flush. The original poster specified 300 coins for a straight flush. When you input 300 coins for a straight flush, vpgenius will tell you that the EV is 97.2646%, which is the same number that someone would get when they multiply WinPoker's result of 116.7175% by 5/6 if they would round properly.

Actually the mistake in my earlier message was mine and no fault of vpgenius. I went back to the original post and discovered the payoff for a straight was specified as 4 and not 5. The default value on the vpgenius site for a straight on this game is 5. As for the original question a return of 4 for a straight on a Double Bonus game is a red flag in itself.
The Super Triple Play return is actually less than you suggest. vpgenius calculates it at 97.1756% with a variance of 64.4697. The reason you cannot simply multiply the five coin return by .833333 is that it does not compensate for the "NOTHING" return of zero with the additional coin bet. Since 0 x.83333 (for six coins bet) isn't proportionately smaller than 0 (for five coins bet) an adjustment has to be calculated and then integrated into the return separately. And in this case it makes an already weak game even worse.
