some numbers that i have...
the way that the seating algorithm is constructed means the zoom pool often runs 3 handed, here is a 3 handed sample
some other numbers from high volume midstakes regs are
sb i was dealt 126k hands
bb 128k hands
btn 113k hands
we all mass table and concluded that it must be to do with how many entries you play or something. These sample sizes show that it cant possibly be to do with 'sit out out next bb'
also on party you have to manually download your hands so some chance its an import error, no idea
