i would say it varies, depending on whether, deer activity, hunger level, etc. usually i like to sit until about 11am, go in and get food and then come on back out around 2 or so. sometimes if i got a good breakfast and seeing alot of deer or feel good about the spot, will try to pull it off until 1pm or so, but usually only do that if im not evening huntig, since leaving at 1 or so and then returning at 330-400 increases chances of spooking them
