No idea ignore them readings was this done outdoors in uncontrolled conditions.

Results show tell tale signs of changing light on chrono ie 100ft/sec+ Plus new rifles barely make 10.5ft/lb with anti tamper another tell tale sign chrono playing up.

I've done the test 3 times now and very similar results?new battery's in the cronograph,I've used the same pellets from same tin,and put 1500 pellets through it so something must be wrong??
Oh and all three tests done indoors.cheers

Light through window/s, a self regulating valve wont give that much spread over a short rate of shots.

I can easily get various chronos to register incorrectly just by altering angle 5 degrees, best seen 160ft/sec drop usually the order 70-90 ft/sec.

Then theres the other problems reading muzzle blast rather than pellet speed, notably the polish things, Caldwell Skans, palchrono etc non immune and could be looking for a problem that dont exist. See 1 a week average like that turns out nothing wrong.
