I always used to dyno them after rebuild to set the adjusters. You can’t expect something newly built or old unit serviced to go back together and match its opposite axle partner. So after a rebuild I would remove the knob off the adjusters and dyno’d them. I would get one in the range I wanted it, then dyno the other unit and set the adjuster pin to match. Once both units matched to within a few Newtons I would refit the knobs in exactly the same positions. This meant that if I altered one by one click I could alter the other one by exactly the same amount by the same one click.
It makes it easy to make specific track based adjustments by counting the adjustment clicks.
it also means that you have a perfectly balanced matched pair.
