Noah - 100 - I wanted to be on the "optimistic" end of the scale.
I only observe from April through October - just do not like observing in cold weather.
And I like DSO's. So in 7 months - we have the moon out half the time. Now we're down to 3.5 months x 30 ='s 105 and at least half are cloudy - so we have what - maybe 50 nights a year that are good. And in the summer that's why I go out almost every clear night.
My guess is I went out 25 times in 2019. Makes each night PRECIOUS!!!!
PS: Then we still have problems with smoke, fog, mosquitoes, poor transparency due to higher humidity levels, etc. How many nights a year are perfect??? 3-5??? Those nights are MAGICAL!!!! And worth waiting for.
