While I still do not know how you got the fitting formula, I understood that you did not try to correlate the 1st and 3rd column of this matrix, but the 1st and the 2nd. That would be even better actually, then I have the underlying X and I can extrapolate the "variance modifier" as I want. Just I have to fix the program a bit. edit: fitting the data between column 1 and 2 (the 1 as X, the 2 as y), with power fit I get a value very near to yours. \( 4.5 \cdot \tt{curProbV}^{0.55} \) For the other part of the curve, having the sum of probability tokens as X and as Y the variance of the second part of the triangle distribution (so, variance between 25 and 400) I found this with power fit (note that the longer equation is the exact solution).
