Elevation, dial DOWN

0.54 MOA · 0.54″

Windage, dial RIGHT

0.06 mil

0.22 MOA · 0.22″

This is your zero, separate from precision: group size and mean radius don't change with it.

Within vs between strings

Within MR: 0.310″; 0.31 MOA
Between drift: 0.340″; 0.34 MOA
Ratio: 1.10×; mixed

Mixed — within-string dispersion and between-string drift contribute similarly. Both dispersion and drift are worth investigating.

Hit probability Collective @ 100yd · 20 shots · MR 0.442″

Assumes shooter dispersion is the dominant error source and scales linearly with range. Doesn't model wind, MV SD, or BC uncertainty — those matter more as distance grows, so real-world hit rates at long range will typically be lower than shown.
