I am trying to do something that requires more finesse than a linear pot can provide at the low end, and a log pot of unknown value is not only not cheap, I don't have any. I wrote this up to simulate any value of pot paralleled with any value of resistance, and it shows the data as % of pot rotation 
vs. ohms (x). I hope someone else finds this useful. File is a zipped .xls file
For those that don't know, I also wrote a spreadsheet for determining bleeder resistor values and filter capacitor size, it should still be here.
