I do a triplicate Satterlee test for my PRS rifle. For giggles, I do hang an OCW type target out front. I’ve used a ProChrono Digital, LabRadar, and both a Sporter and a V3 Magnetospeed - both mounted to the barrel as well as on a free-floating rod mount.
Here, you can see plots of one of these triplicate tests with the corresponding targets. You can see within the table, as well as depicted in the chart, the variability among each of the replicants, some charges exhibited a Range (ES) of 2, some a Range of 28. This variability suggests that ONE shot of each charge isn’t sufficient to determine a representative speed for each charge weight, and such, one shot of each charge is not sufficient to truly define nodes. In this test, there are 3 nodes depicted. You can probably guess which node I chose to use for competition.

Target array is 41.0-41.8 on top row, L->R, 42.0-42.4 on bottom row.
