Then you ain't figured it out. Deer behavior is not random until they start getting heavily pressured or caught out of their home range. During the heat of rut, I have seen bucks 5 miles or so from where I know they spend most of their time. If they get caught there on opening day their chance of escaping is mostly to run and attempt to get back to their core and known places of safety. This is where "patterning" does not work. But when deer are in their home range, they bed, feed and travel with consistency. Many times with mature deer, it's because those areas have shown to be safe.....one reason they have lived long enough to mature. Mature deer don't randomly find white oak acorns when they begin to drop.....they know where they are and when they drop. If you do too, you have a good spot. Mature deer don't randomly chance upon good escape routes, they have used the same ones for years. It may not be cognitive thinking, but a habit developed because it works. Same goes for bedding areas. deer select thease areas for a reason...proximity to food and cover, and the ability to monitor any actively within it, whether it be other deer, predators or us. Again, when deer are heavily pressured and pushed beyond what they are familiar with, or blinded by lust during rut, all bets are off. This is when even a blind squirrel can find a nut and is usually when folks who don't prepare get lucky and get a deer. For half a century I have hunted a large piece of public land. On opening day, knowing where the primary escape trails are and where other folks are entering the area are key to success. But even then without control of where other folks may choose to stand(usually right next to you) or travel will change patterned behavior. even the best stands is a bust if and when you are surrounded by folks and being cut off unless they miss. This is when I pick a not so obvious stand that is difficult to get to. I don't see as many deer, but odds are I will get a chance at a deer. Later on when the pressure dies down, the deer will go back to what they are familiar with. While the rut has been killed by hunting pressure and the deer are now basically only active during darkness, if one has patterned where they eat and sleep, the odds of success is much greater. I like to wait till the last weekend to sneak hunt areas of this public land, hopefully with nasty weather to help. Because of years of patterning where deer go in this area when pressured, it helps me to avoid the other 90% of the area where they are not. Years ago, we called this "Woodsmanship".
