I note that the graphs and calculations are in absolute T-chips rather than in EV. This has the tendency to skew the "difference" unnaturally high, and causes players to think the cards are rigged against them when in fact they are not.
This is because most every tournament you enter ends with an all-in loss and elimination hand, where the relative chip count is high... and in those elimination hands, the hero (usually) has positive equity and (always) loses, pumping up the "difference" by an amount that is disproportionate relative to the "lucky wins" he may have experienced earlier in the event.
That's why virtually every player's graphs show a "difference" line that is far greater than the EV line... and that's not good.
A better way to calculate it would be on absolute EV percentages, and then graph that so that all hands are treated equally, regardless of the size of the blinds relative to the stacks. Here's what I mean.
In the "Hands" view in your program, you have columns for Equity, Expected, Actual and Difference. Instead of using T-chips here, though, to make all hands equal you should have Equity, and absolute result (without regard to the actual chips won or lost). If I have an equity of 53.9%, and I win, my expected is 0.539, and my actual is 1.00 (I won 100% of the pot). If I split the pot, my actual would be 0.50, and if I lost the hand, my actual would be 0.00.
Then, you're truly comparing luck... because at the end of a statistically significant run, the sum of all "expected" values should closely match the sum of all "actual" ones.... without being skewed by the nature of tournaments, where the last hand is almost always a loss. In the end, I'd want to see a red line for "difference" that hovers very near zero, and green and blue lines that are in close proximity overall, but that separate briefly (representing short term luck).
Then, if the red line has deviated significantly from zero over the long haul, you'd know whether you were running good or bad. If the red line trended up, you'd be running good, down, bad.
It might be best to have a toggle option available, one to show absolute chips, and one to show relative EV without regard to chips won or lost, especially in the SNG version.
I hope I've been clear in explaining this. If you have any questions, please let me know. Keep up the excellent work.
