Given the muzzle velocity, bullet weight and B.C., and a 100m zero, Strelok+ gave a readout that was within 2 MOA at 2000m, so pretty good in my book. It also has a trajectory validation option, so when I told it my drop was 98 MOA, not 97, it worked out my muzzle velocity was 2740, not 2750, or something along those lines.
