I try to answwer all your questions.
1) Strategy Points = raw Partypoints. (Without the Queen+ multiplier)
2) You can do whatevery you want with your Partypoints. It won't affect your Stratgypoints at all. All raw Partypoints count. (it doesn't matter if you redeemed them for money or tourney buyins)
3) Your Pokerstrategy status is calculated by the raw Partypoints you made in the last 4 weeks.
4) If you think there is a mistake. For example you have 100 raw Partypoints by 1st August and the Pokerstratgy status is updated up to the 1st August as well and there it says you only have 75 them please contect our support. There could be a mistake within our point lists.
But please check that the Pokerstratgy status is really the 1st August and that you only counted the raw Partypoints from the last 4 weeks.
5) Currently the Pokerstratgy Partypoker point status is the 21. of July and not 1st August yet.
If you have further questions or if I explained something to unclear please let me now.
