Yes, I have done a similar analysis. It can be found in my pai gow poker appendix 2. There are some important difference between my strategy and his. Wong’s is much more detailed, considering the highest two singletons, while mine considers only the single highest. Wong also differentiates between whether the player is banking or not. Finally Wong’s book is based on the California game with no 5% commission, unlike my strategy. I do trust Wong’s work and don’t disagree with his table.
