Bankroll Question

I currently play $28 + $2 super turbo's on full tilt on a $5000 bankroll. I am increasing my roll by about $200ish / week + rakeback. I play enough to 200 ftp / day, then I stop. At what point should I be moving up to $160 + $9 super turbo's (talking about bankroll)? I am wanting to skip the other super turbo's with alt. buy ins such as the 40-50 game because I'd rather play a slightly lower buy in knowing my ROI in these are solid and I can beat these games. I am fully aware that there is a token one for $69 + $6, but Id rather avoid those games. I am thinking a bankroll of roughly $15000 would be fine to start these games, but I am not 100% on that yet.

I like this:

Hey thanks for the chart. I really like the chart and I will use that as a guide for bankroll management.

how many are you playing at a time? that also makes a difference..

I 2 table, but the other table is most likely a tournament with a very low buy in relative to the super turbo's I am playing. And the chart looks good, I might use that as a guideline.
