Thanks. I'm glad you like the tool.
This aspect of the salary estimator is an odd duck. I agree, it would seem that the coefficients ought to all be ≥ 1. But wozzvt's analysis of the extensive data gathered suggested that there were these slight oddities that you observe. Rather than trying to adjust them to fit what I think ought to be the case, I'm inclined to let the analysis stand (just like with passing for bigs).
Yes, every once in a while it would seem like adding certain skills would make a player "cheaper." But we are talking minuscule increments on a blunt instrument. An example: my main trainee (PG) has the same salary whether I put his SB at 1 or at 23. And a 193k SG with 1SB swings down to 190k when you up his SB to 25 (SB on a SG being the coefficient furthest below 1). But that much change can also happen due to the random factors associated with salary changes at a new season.
As always, you are free to adapt this tool for your own use. What I think is valuable about it, though is that it is based entirely on wozzvt's data collection and analysis.
Perhaps in the next version, I'll change the salary rounding after a certain point to increments of $5000. That way people will understand better that this is most certainly an estimate. What do folks think about that idea?
