This time on an overcast day instead of the bright sunny day as before. This time I came up with 2791 FPS. Now my program and my actual field data matched perfectly. I learned a lesson about very bright sunny days and chronographs. I was using one of the best chrono's made the Ohler 35
Yeah, a clear blue sky & a bright sun directly overhead can cause issues sometimes.
I have a PACT & on those kind of days, I use translucent shades over the skyscreens.........usually fixes the reliability problem.
