is it ok to use a chronograph on a cloudy day? Our weather here has sucked lately and a sunny day is pretty rare this month. I wanted to test some APP-Round ball numbers.

They generally work just fine on a cloudy day. You can shoot without the skyscreens if there's no direct sun and the chrono isn't under trees.

Mine prefer cloudy days

I have best results on cloudy days. Lee

Im not sure but there is a chance i will find out tomorrow.
