The real story about 50%+ ROI

[Bozeman]

Here are the important points that I believe hold true for SNG results:

A) 50% ROI is possible (as is 50% ITM), subject to some important constraints, see below
B) If you can make 50% ROI, you can make more $/time at the next level up
C) At the highest levels (I have a lot of experience at $215 and $109 levels), these numbers are not sustainable
D) Statistical significance: to be better than +-10% statistically certain of your ROI, you need > 300 SNG's (possibly >> 300).

Therefore: no one should play enough SNG's at a particular level to be statistically certain they are 50% ROI or better.

Caveat: massive multitabling could negate some of these arguments.
