CP high with a pass?

[Phat Mack]

I've put in a couple of hours playing Chinese Poker, all high, where the players pass two cards: left, right, across and hold.

Has anybody played or investigated this game? I haven't played a statistically significant number of hands, but it seemed to me that the hand values were slightly higher. I don't know whether this was because of the pass, or whether it was because players were setting their hands sub-optimally. I'm not sure why passing cards would skew hand values, but I'm still thinking about it...
