I picked up a short action customs final scope level recently and finally got out to run a few scopes through their paces this afternoon. I used a box to bench precision “snipers hide” target that had 10 mils of vertical scaled for 100 yards.

Figured I’d share a few data points. Results were pretty good.

Bushnell LRHSi 4.5-18: 10 mils on the turret got 10.1 mils reticle adjustment. The slight error was consistent across the adjustment.
Bushnell LRTS 4.5-18: 10 mils on the turret got about 10.05 mils adjustment.
SWFA 3-9 #1: perfect
SWFA 3-9 #2: clicks in the first 4 Mils were a bit strong such that it had moved 4.1 mils in the first 40 clicks. But from 4 mils to 10 it slowly balanced out to where it was basically on the nuts at 10 mils.
Bushnell LRTS 3-12: by 10 mils it was just barely perceptibly strong on the adjustments. Maybe 10.02 mils? Call that one good.
Vortex PST g2 5-25: about the same as the 3-12 LRTS. Just bought this used for a 22. Was a bit of a **** getting clear and eye box seemed tight.
Bushnell DMRii 3.5-21: perfect as perfect can be.
