Can someone explain to me why a site that allows the house to have both seeds/keys and can use that information against player money 'invested' in the bank's position, wouldn't be suspected of being a scam? Per your SD and other statistical analysis, it could easily manipulated by the con in several ways. One way would be to intentionally lose a number of bets to create a distribution to their liking and simply betting more less times.
To me it seems like a perfect setup for a con. I'm not saying it is a con, but if I were a betting man....
