Help Me / Re: Dr. Neau Formula in Tournament Director

Like a lot of features, it was originally intended to showcase a single specific use case, but then was modified to make it more flexible. Often that results in something being a little more complicated to use, sometimes not. The idea of the Test Range window was originally to show the points a player would earn for each possible rank, 1 through n (n being the number of players in your tournament), for your formula. But then it seemed logical that one might want to see how the points change when other factors change (instead of rank), so it evolved to a tool that allows you to see the points computed while one variable changes from one value to another at a certain rate.
What ends up making this window confusing, however, is that many formulas, even the simpler ones, have other variables involved that must be set in the Points for Playing window first, else you will not get the results you are looking for. For example, here is the Test Range window testing the simple formula n-r+1:
I've set it to display the results of the formula for ranks 1 through 10. But the results don't look right. First place only gets 2 points, and the points start going negative at 4th place? The reason is that n (number of buyins) was set to 2 in the Points for Playing window. So to get the right results, I need to close the Test Range window, change the value of the buyins variable, then try the Test Range again. I changed buyins to 10 and then opened the Test Range window again:
Much better.
