Curtis,
A very well thought out analysis for defeating a quarry that is visual reliant, like human beings. Unfortunately most of the quarry that I bowhunt relies upon olfactory (nose; sense of smell) more so than the visual sight.
Although when hunting man a Marine sniper must contend with his quarry's greater intellect I find that hunting critters that smell better than a blood hound, despite being vastly inferior in the intellect department, is equally as challenging. The honed survival instincts of God's critters relie more so on that sense of smell than that sense of sight that human beings have come to trust, almost exclusively.
Still, I like your analysis of taking advantage of the natural condition, moving with the natural flow of the wind. There certainly is merit to your observation from a visual perspective.
