I've been playing for about a while, but I started to get really really serious about 4 months ago, and purchased PokerTracker. I know I need to raise more rather than limp, and this is mostly 6max, with some Full Ring. Also, this is mostly 10NL, and I have the BR to move up to 25NL, but do these stats show that I'm ready? Any tips to improve my ring game skills will help a lot. Thanks for the time.

Small sample + mixing FR/6max make the answer pretty much unpossible.

Will say that narrowing the VPIP/PFR gap is always a good thing. Stop open limping. Steal more.

I'd have to agree. You need to limp a little less and raise a little more. Your af might be a tad low as well.
