Facts:
1. Pseudo random numbers will produce hole cards, flops turns and rivers which over a reasonable sample size will show the expected distribution. I would bet 10BTC against the idea that analysis of enough data from hands at seals would show abnormal distribution. If someone is interested in this I will detail ,y terms.
2. SWC stands to make shittons of money even charging as reasonable a rake as they do. It is in their best interest to provide the fairest environment possible to their regulars and recreational players. Nothing is really more important than trust for them. The client etc all come in second at best.
3. There are surely many many thousands of dollars (possible understatement) being held in wallets by seals. If they wanted an unethical payday they would disappear with that money. They have not done this.
As a player at seals for well over a year, I can vouch for the quality of the people running it. They have earned my trust. And as I said... To my analysis the distribution of cards is absolutely normal.
