I think I'm ready to move up

[Me and You]

Hey all been playing .25-.50 and I believe I have conquered it however my sample size isn't great.

Here are my stats:
Hands: 6079
VP$IP: 22.45
VP$IP SB: 43.32
Fold SB to Steal: 83.33
Fold BB to Steal: 45.45
Att to steal Blinds: 23.74
Won$WSF: 29.25
BB/100: 3.52
Went to SD: 40.54
Won$at SD: 49.72
Preflop Raise: 8.44

I've read that $.5-$1 isn't that much different and I have the br for it. So should I move up or stick it our a few 1000 more hands at this limit?

Cheers
