That is super interesting and the first time I have seen that.
I’m a USPSA M, can clean the FAM, did a Failure to stop from surrender concealed in 1.35s, and can put 10 shots in the 10 ring at 25 yards freestyle on a timer and 292 on FBI Bullseye.
It seems to me that the equivalency scale is quite accurate. I’m at the point where when running on a field course, I don’t think about the shooting. Just the footwork and course.
