Perhaps a little reckless banking so close to the ground, but you have to realize this guy does the same exact thing 30+ times a day, change days rinse and repeat, same location even- I doubt he is guessing wildly on what will happen. Having done this sort of flying quite a bit myself, I know that what seems kind of uncontrolled is actually pretty controlled most of the time. It just looks crazy to someone who doesn't do it. Many aerial applications appear more wild than they actually are.
