There is no such thing as "instantly" there is a delay until an edge is detected, a delay before the software has looked at the current position and direction and a delay before Z starts to follow the reversal, the sum of delays is a strain on the tap, making all numbers less will reduce the strain.
I have made a 50 slot wheel for my 5 axis in readiness to try rigid tapping. 200 counts per rev, Z screw is 1mm per rev, that is about .2 thou from the encoding and more for any software delay to Z command. Someone with a .2" pitch screw and 8 slots has a possible error of 6.25 thou before seeing the encoder edge. not something I would try.
