Your results are great then at 2-3 tables.

Sounds like you havent had a decent downswing, so that might change things a bit, but If I were you Id carry on and only make very minor changes to your game, make changes slowly, and look at your current hands stats in pokertarcker

You know you should be raising more, and over time, depending on how certain hands are performing for you, start either cutting them out or raising with them, some hands I feel are ok to limp, if you easy fold them when you miss the flop, however when you start raising with them you feel more married to them and end up losing more with them, these are the hands you either fold pre flop or raise instead of your current limping to much.

If you make big changes to your game, and start raising alot more, and this coinsides with a couple of bad cards sessions, it can screw your game up,
