I feel like the transition from .5/.1 to 1/2 was pretty smooth.

My attempted moves up to 2/4, however, have not gone so well. 2/4 is MUCH more aggressive, and the amount of 3-betting preflop isn't even comparable. I feel like I rarely got 3-bet at 1/2, even though I was running at 25/20.

If I try to even run close to 25/20 at 2/4, I'd expect to get 3-bet almost every time I raise.
