Well, you will know how the pot was wired but, yes, minimum capacity = minimum reaction = minimum volume.

Please can you just confirm where the resistor would go, is it between wiper and hot end?
Yes. Because the resistor shunts the top end of the track it plays the greatest part in determining the value and rate of change of that section whereas the value of the bottom section will increase normally and, therefore, more rapidly.
With those values, the value of the bottom section will increase from zero to 17% of maximum in the first 10° of rotation; by 13% in the next 10° and 11% in the next. The rate of increase will continue to fall with further rotation: 9%,7%, 5% dropping to an average of 2% per 10° for the last 50° of travel.
