Yea what he says goes whether I agree or not. Its not like these deer are anything to get too excited about. I'm more interested in being able to take 3.5 year old culls, but we have an age limit of 4.5. I'm guessing he's trying to get the overall herd age higher maybe??
Sounds like he's trying to increase the buck/doe ratio or simply protect younger bucks. If the herd is at or below carrying capacity and sex ratios are balanced, I cull starting at 2 1/2 based upon score and points, not age. If a deer reaches 4.5 on our place and isn't at least 140 inches, he's a cull.
Culls
2.5 less than 8 points or 85".
3.5 less than 9 points or 115".
4.5 less than 9 points or 140".
There are exceptions, but these are my culling guidelines.
