Hey guys, I have a good guess as to what is happening. Note: I don't play on Party Poker, I play on WPN but have noticed a similar inequity of hands dealt.
My HM3 sample from Blitz on WPN:
My theory is each fast fold table you play on runs multiple "sessions". Let's just pick 6 as a maximum arbitrary number of "sessions". In reality this could be higher or lower, but the idea is to have enough sessions running concurrently that you (and every other player) will always be able to get dealt in to a new hand the instant you press fold.
Let's say you play for an hour and then decide you want to take a break, so you hit 'sit out next bb on all tables' which should mean the maximum number of sessions (6 in this case) are now running.
Now let's picture what position you were in for the last hand you were dealt in each session.
Session 1: EP
Session 2: BTN
Session 3: CO
Session 4: SB
Session 5: BB
Session 6: MP
Let's say you're currently in session 6 and that session 1 happens to be the next available session after your hand from session 6 ends. You are now in the BB on session 1 so you get sat out and miss the following hands ... Session 2 (EP through CO), Session 3 (EP and MP), Session 4 (EP through BTN), Session 5 (EP through SB), Session 6 (EP).
All together that would be 14 hands you did not get dealt in to that were not the blinds and 1 SB hand in session 5.
This could even be more complicated if the sessions you are active in are able to switch between other tables you are playing on - but I believe this theory would explain the variations people are seeing.
The solution is that instead of "sit out next bb" the poker sites should have an additional option "sit out at the end of all sessions" - so that you can choose the option that fits your situation.
Needing to end a session quickly or temporarily? Sit out next BB and you will immediately sit out the next time you're dealt to the BB. Just want to end your session but still get the hands you paid for? Sit out end of all sessions.
Resuming your table(s) if you sat out in the BB should remember the positions from each of your session when you resume, deal you in to a new session that matches your next position for the respective session, and allow you to use the sit out all sessions option later so that you get all the hands you paid for even if you need a break.
If there are sites with fast fold this is not happening on, my guess would be those sites have enough volume to not need multiple sessions - or there is a delay of some sort between hands to keep everyone in a single session - or they could have just implemented the solution I mentioned (alternatively maybe sit out all bb just deals you in until you play EP for each session, then sits you out)
