With so many factors not taken into account (i.e. doe movement affecting bucks, wind direction, scent control of hunters, bucks getting spooked by hunters, etc.), I wonder what the real-world value is from this study. In an enclosed area with controlled hunter access, I guess it will relate. But in public lands with lots of hunters, I wonder if you can apply a study such as this. Not that the study has no merit, but that a myriad of factors will potentially change the results.
Seems to me that the return rate for this study is probably BEST CASE scenario, and in a public land/club setting with the other variables, the time could be much longer.
