When the cows are laying down, so are the deer. That's the only chart I've ever used.
And thats a good one. I watch other animals too. If the squirrels, birds, and everything else is moving the deer are moving too. If it sounds like I am sitting in a morgue I have never seen a deer or anything else after hours of sitting. If the crows are out in force, the deer will be moving also. I've never had luck going by published data cause I don't think a deer can read when he is supposed to get up and move.
