I seen from the beginning this question would have too many variables.

My grandfather has probably well over 400, 81 and still gets out hunting just gets the grand kids and younger folk to come get the deer for him now.

My father due to lack of time being able to get into the woods for nearly 30 years has between 75-150. Might be a little high for him. He is 56.

Uncles and such would say with a little more time available to hunt and mid 50's they have averaged over their lives between 200-300.
