In practice, dividers and multipliers can be used to shift the line trigger backward or forwards to
adjust the rotary encoder distance per tick.

For example, if each rotary encoder tick represents 10 mm of movement, a multiplier of 8 results
in each tick equaling 1.125 mm (1/8); if a divider of 5 is then applied, then each tick is 6.25 mm
(1.125 x 5). Therefore to calculate the value of each tick:

This allows using a simple fraction to adjust the encoder
