Ok, first of all, in the past I've managed to turn my 50$ from pokerstrategy to 1500$ using the SSS on mansion. So I assumed I played 'perfect' SSS, I posted a lot of hands in the past on the dutch forum, think I erased any leaks, never doubt what to do,...
Recently I restarted on Full Tilt with a ~35$ roll playing 12 tables at a time.
Here's my graph:

Here's my stats:

(the 38PL hands were actually only 2 hands played before I realised what was happening there ♦ )
I use Leo's starthandchart which is basically std. SSS but no KQ/77/88 from the blinds and some steals/resteals+completing with PP/Axs/... when given the right odds.
I know it's partially downswing but I'm seriously doubting my game because of this.
I know it's not a very large sample size but 8k hands seem like a decent size to reconsider some things.
Can anybody explain this?
