Rate of fire ladder testing

[SNOW JW]

When doing your ladder test with say a labradar do you get better results waiting a bit between shots? Have about 15 rounds I want to test to see if the 6.5 guy method works then validate at 300. Thanks

I usually fire have someone run down and mark the shot, or do it myself and then return. Usually 3-4 minutes or so.
