STT ROI's

[Zim25]

Over the last 200 games played (I know this is not alot) I have 38% ROI at the 5.50 level on UB. How do i know if its time to move up, and how long shoud give it? (how many games)

My thoughts are if I have even a 19.5 ROI at the 11.00 level, I'm making more money. Or 10% at the 20 level.

As far as skill goes I feel I crush the 5.50 games. My bubble % is 84% and rarley get my money in bad. (not never)

So how many games and at what point do I move up?

Do I need to make any big adjustments to my game if and when I do?

EDIT-also is PAHUD usefull for STT's?
