Does your data normalize for man days in the woods?

I used to be in a club that would mention similar statistics but the way they prepared their data was awful. Most of the members hunted in that same 2 week time frame over the 10 years so naturally the kill data showed that’s when the most bucks were killed. A whitetail rut is determined by photoperiod so just that fact would vary the peak of the rut 4-5 days year to year. For instance, last year the sun set at its earliest point on December 9th last year. This year it hit its earliest set on Nov 30th. If your deer herd sticks to that photo period then they’ll be going almost 10 days earlier this year but in reality it’s right on time.
