My Grendel Barrel is "Slow?"

[Klem]

mv1,

Good chance it's the chrono. Optical chronos are notoriously fickle. I have a folding optical Chrony and gave up using it in the daytime. I use it at night with LED strips under the skyscreens. The difference in reliability was chalk and cheese, no more odd readings and lost shots.

I upgraded to a LabRadar but the nighttime chronying works fine.
