Based on his numbers, this represents about 20k hands played. Not huge, but fairly significant...my experience has been that PT data tends to normalize around 15-20k hands. So, while some of it is sample size, the larger issue is how the hands are played, esp AJ vs. AJ sooted. AJ sooted can be a huge loser if you are always chasing a flush at any cost. A2 vs A3 sooted is a coin toss and therefore one hand could be more profitable than the other at any given point in time. Not sure it has anything to do with "rigged"...just depends on how you play the hands in my opinion.
