Good avg. ROI?

Risking putting myself 'out there' for limited or unlimited scrutiny:

I was wondering what the consensus is on a good average ROI for someone like me who plays mainly sit n go's at low level stakes?

I tend to play $3-$10, 6-18 player sit and goes on Stars. I am currently sitting at about 12% ROI. And if no one laughs or makes too much fun of me I will post my sharkscope graph. This does not take into account my multitabling which I'm not too sure what my ROI is but it is positive.

Just wondering what you all consider fishy or solid or what?

Another sort of related question, what kind of bankroll management should I be considering? I have only ever deposited 50 bucks to get started and made a few modest withdraws. I have about a grand in my account.
