You know, thats an awesome question. I'm wondering the same thing. I was playing perfect basic strategy. I had my table in front of me and whenever I forgot what I was supposed to do I'd refer to the chart. There'd be no reason for it not to be legit, just having the dealer hit on soft 17 and continuous shuffle means that the game is horrible enough but I'd watch myself just go on huge swings that had me questioning whether the party blackjack is 'fair' . .
