To what extend can we reduce the influence of variance given this sample size and the relatively variance-friendly format in comparison to MTT's with larger fields?
Can I expect around the same ROI/at worst see it drop of a bit when I put in similar volume next month, or is there a decent probability that it still drops a lot? I'm probably the best player in my player pool so I'll be fine, but I was wondering this given the high ROI. Can't really compare it to previous results as my volume has been all over the place the last couple of months.

The following is from a SNG program I wrote, which provides an analysis of your performance based on the investment, prize structure and your ROI. Because of your good ROI in 385 tournaments, you can be pretty confident that you are a winning player with only 50 tournaments showing a profit. The chance of going bankrupt in the next 500 tournaments starting with a bankroll of 10 buy-ins is 5%. This was based on the assumption that when in the money you finished 1st and 2nd 50/50.
