You're win rate is decent. I tend to move up stakes when I feel comfortable gambling at that level. If you feel like you are playing better than the other players and don't mind slightly higher swings then just move up and try it.

If you have only played 46k hands at 400NL then you probably want to get more experience before 5-10. 600NL isn't much different to 400NL I wouldn't have thought, although I don't play Party.
