Should I move up?

[nykbbal]

I have been a mainly MTT player for the past year or so without ever getting into cash games and have recently started to dabble in the micro stakes, particularly .05/.10. I have been keeping some stats from my play on these tables and was wondering if it is time to move up from these stakes.
Total hours playing: 28.1
BB/hr: 10.7 per table

Those are the two main stats I have been looking for. If any others are more indicative of my ability, please let me know.

Thanks!
