As Squirle hunter pointed out, I think that mid-day peak generally only occurs in heavily hunted areas. I've been tracking mature buck movement via trail-camera on my place for many years, using camera pointed at as many different types of deer traffic areas and bottlenecks as I can identify, and I've seen very little mid-day movement. Some will argue, "Well you just don't have the cameras in the right spots." Maybe, but highly unlikely.
Yes I've pretty much given up on sitting mid day. It's never paid off. Daylight to 10:30 and 2:00-dark are my times to hunt.
