i haven't read the discussion that precedes this post, but would just like to point out that you're running good. i'm not saying this to be an ass because you're obviously doing quite a few things right, but don't expect 15BB/100 on a consistent basis. though i'm sure there are many players who CAN do that on a consistent basis at 25nl and even 50nl, you're W$SD and WTSD stats indicate that you're out flopping your opponents more than ought to be expected over a large sample. of course this may have to do with you're relatively weak-tight preflop play, though seeing VPIP'ing 20% of flops isn't really THAT low.

so on to actual advice, be more aggressive preflop, stop open limping (a 4% VPIP/PFR spread from UTG is pretty ridic), and abuse that damn button son. nobody knows how to defend their blinds in a +EV fashion at these stakes , so you should be ATS'ing like 2x's what you are now. could prolly start experimenting with 3b'ing lite
