I have followed this very close starting in 1999. I personally have found it to be very accurate. I will however tell you that alot of factors can make small to very large changes in the deer behavior along with this whole theory. Weather is probably the most pronounced. If you get a warm day or week in there, deer movement will slow and sometimes almost seem to halt. I found that when the rut falls right in a major hunting season, like it often does in SE Minnesota, BOOM, rutting activity slows a major amount. Other things like cold weather earlier in October won't start the rut, but will bring bucks to their feet and seem to spike their curiosity. So yeah, there may be something to it, but lots of things can make it hard to understand unless you are really out and hunting every day from pre-rut to post-rut. Fortunatly, I have had this opportunity for the last several years in Iowa, Wisconsin, and Minnesota.
Oh yeah, 15th OCT seems a little early. Should be more like 15th NOV. Maybe they Typo'd.
