by looking at your stats alone it seems to me that you could make some preliminary overall clean up with two easy things: 1) you're playing too many hands for 25nl. 25nl is a game in which bluffing is difficult and people play very straightforward. Therefore playing 35/25 or something around there is not profitable unless you are really really good. 2) Im not sure im completely understanding these preflop stats and correct me if Im worng but you are losing all of your money when the villian is the raiser?--If my undertanding is correct then my inital reaction would be that you need to tighten your calling range. If you think about calling versus being the initial raiser, your range needs to be tighter than theirs for calling to be profitable. Also, im not sure what your position stats would look like but I would guess that you are playing too many hands oop. Not playing as many hands oop is a HUGE factor in winning at 25nl because since people play so straightforward it is so easy to get reads in position
