without yelling, sorry im a noob.

do you calc. your roi by average take back? ive played about 20 5+1$ SnG's and im about even from where i started.. so my ROI is 0% right?
If you take first and get 45$, is your roi like 700%?

So if i get first and then bust out twice... so ive gained 27$ in last 3 tournies is my ROI for that day about 400%?
