Thanks for the info. That clears things up a little more. So the pot provides some low and high resistance values corresponding to fully retracted and fully extended positions of the output shaft. So the increased travel pot that would replace the stock pot, needs to provide the same two extreme resistance values. It seems that the actual centered position of the pot may not necessarily lie at the required centered resistance value, but instead only be the resistance value half way between the extreme values. In other words, you could use a pot with a higher max resistance than necessary, as long as the range needed is included. It seems that resolution is now in question, so that maybe to optimize that, I would need to use a pot having pretty close to the actual resistance corresponding to max throw of the stock pot. Then whatever number of turns of the output shaft desired would have to be geared to the number of pot turns corresponding to the resistance range found previously, right?
