I have noticed I don't seem to make the correct percentage of flushes when I flop two of my suit. With 9 outs it is roughly a 36% chance to complete or about one in 3. I have only been tracking for the past 6 but have not hit one yet. Not that it is unique to me either. I have yet to see one win. I see nut flush draws that don't get there vs made hands but no magic flush hits.

Another player said the site favors pp over draws of any kind. That seems to be less predictable but may also be true. The flush draw is anecdotal only, my sample is way too small to mean anything, just a curiosity.
