Whoa, so it allowed a bet of 9 BTC?? How is that possible?
The restriction is on profit, not wagered. You could wager >1000 BTC if you wanted, as long as you weren't trying to win too much
To me ~0.29% seems more realistic than 35.3028752%. So assuming the bet was a max bet (which it probably wasn't but was close) the house overbet by a factor of roughly 120x. Good job!
While it's more realistic, I think it doesn't pass the sniff test either. I believe the absolute lower bound would be the house edge, which in this case is ~0.92%.
