Winrate in general and especially over a 15k hand sample is overemphasized, imo. Though somewhat rare, variance can make an expected 10bb/100 winner be a -10bb/100 loser over that sample size. In about 80% of cases, a person with an expected 10bb/100 winrate over 15k hands is just as likely to be at 1bb/100 as 20bb/100, so in all honesty a difference of 20bb/100 over a 15k sample size isn't really telling you much about your actual skill level.
This is a good tool to help you see what range of winrates become statistically relevant for a given sample size:

Instead of winrate, focus on reviewing your hands and making sure you are making the correct decisions, even in hands you are winning. It's always possibly you could have extracted more value, or you made the wrong decision but ended up with a nice result.
As far as when to move up -- I would agree with others to say you should aim to move up as soon as you feel comfortable doing so and your bankroll allows (probably at least 25 buyins, and moving back down if you drop below 20 for the level). If you don't like the new level you are at or drop a few buyins super fast, don't be afraid to drop back down as almost all long-term successful players building a bankroll responsibly have had to do it.
That's great advice mrmonkey - thank you!
I have been reviewing my hands after every session. I usually look at the biggest losses but also look at a couple where I think I missed value and have been posting some of these in the HA section. I have made some mistakes - especially when it comes to missing value. But most of my losses have come from AIPF with premiums AA & KK and a few against short stacks with AK. There have also been some sets losing to higher sets and even a full house losing to villain who flops quads.
Thanks for the link. Really puts things into perspective.
