For example, let's take a 340 degree single turn pot....
Roughly we know it's voltage is from 0v to 5v.....
So if it we take 5v / 340 that means it's 0.0147 volts/per degree.
Take your voltage reading and divide it by your volts per degree to get your angle.
300 degree pot would be 0.0166 volts per degree.
270 degree pot would be 0.0185 volts per degree.

I like your way of thinking
I'll use that
