Would you ever be tapping that slow? If you are - then yes - higher resolution or try interpolation.. (Will that be bad in rigid tapping reversals? Threading on a lathe interpolation works great - but that is one direction...). The green machine had a gear tooth encoder - about 40 ish teeth. I never tried running it that slow rigid tapping - but I did initially use it for non-circular boring. It did OK at around 10 to 50 rpm but you certainly could see the resolution in the cut.. I did rigid tap with it - but pretty high rpm with no issues..
