Stephen,
I have found that most deer bed in areas they feel safest. This has alot to do with wind
Next time you see bedding patterns like this, pay attention to the prevailing wind in the same area and the wind at the moment you jump the deer. The next time the wind is the same (speed and direction) try hunting the down wind side of the area and try to be on the down wind side of the deer's most likely direction of entry (morning) or exit (evening). You never want to hunt directly on a bedding area, always 100 or more yards away from the area in any funnel you can find that deer might be using to enter.
We also push deer out of their known bedding areas to other bowhunters who are waiting along normal escape routes. You would be surprised how predictable deer are when they are pushed out of bedding areas. Again, wind is very important in this case as well.
Happy Hunting
