very good info thanks fort sharingSince you asked...
I went thru this little exercise a few years ago [2013] with another guy who ran my numbers.
Me and my buddies took 22 elk [archery] in 10 years
[2003 - 2013]
16 harvests were in a moon phase of 50% visibility OR LESS [some were new moon, 1st quarter, etc] 6 harvests were in a moon phase of 90% visibility OR MORE [very near or at full moon]and quick research shows 3-4 days on either side of the full moon date have > 90% or more. Shall we say 7 days are 90% or more visibility? And approx 14 days have < 50%
Category Observed Expected # Expected
1 <50% 16 11 50.000%
2 >90% 6 6 27.273%
3 50-90% 0 5 22.727%
Chi squared equals 7.273 with 2 degrees of freedom. The two-tailed P value equals 0.0263
According to the analysis we did better than expected when the moon was dark, about what you would expect near a full moon, and less than you'd expect (zero) when the moon was out but not bright. It shows some evidence that it's better hunting during darker moon, but I wouldn't schedule a hunt around it.
Good luck
