Hi Bradley,

Yes they can be more controlled by measuring each note's pitch deviation.

Yes, there is a difference in compensation ( a better word than overpull I
think ) That is why it is set as a percentage of the pitch difference. Yes
location in the instrument makes a difference with the mid treble requiring
the compensation.
