1) I think what you are asking here is if there is rollover on ring table poker winnings. The quick answer is no. But if you are in the middle of rollover, the points you win in that "batch" will not be freed up until your rollover is done.
2) I believe it is 10% up to a max of 6pts per pot.
3) With rollover this is a little harder but yes you can assess this by looking up your points history and looking at the in/out from Poker. For rollover, I have already asked about this and SBR is looking at this but right now the only easy thing right now is to record total losses. For the smaller tourney wins, this is more likely than the bigger wins. For now, I would suggest just good note taking and if you religiously logout from ring table sessions, your point summary will give you pretty good data on this.
