Are you sure about ROI

2. 40% is sustainable at lower limits.

It may be (though only at the $10s, I'd guess), but I've never heard of anyone with this ROI and a big enough sample size at this level. "Well, of course not", you say, "people who are soundly beating the low limits tend to move up quickly." Yes, but the fact remains that since none of them stuck around at the $10s/$20s long enough, their ROIs are suspect.
