I think the closer to 1:1 the buck ratio is, the better peak breeding and the wind-down period is for hunting. The build-up period can be good if you hit it right, but a hot doe a mile or two away can also vacuum in every buck in the county looking for that first piece of the action. If you're not lucky enough to be in on that action, you are out of the action and the hunting can be totally dead. Low population, low ratios, you don't really get a lockdown. Individual bucks certainly lock down but over the terrain there are always some roaming looking for ladies.
As the doe ratio climbs higher and higher, that effect is lessened as there are more does to go around in the build-up period. Which I think makes that late October buildup period hunt better in those areas. Conversely, the lockdown component is magnified because if there are many does for every buck they don't have to look hard for the next one when the lady they are with kicks them out.
