Sounds like the guy needs a lot more then just a week of practicing with a bow, it sounds like he needs to shoot his rifle as well. I have a buddy that "hunts HIS own property" he pulls out his bow about a week or so before season and shoots a few times a night and calls it good.. I've tracked way to many deer for him with no success. I find it absolutely stupid as well as unethical to practice this type of habit.. some people have no common sense and respect for the animal... I probably send 20,000+ arrows thru my bow in a year.. In my opinion practice makes perfect and that shouldn't matter whether you hunt with a rifle or a bow, its all about respect and ethics!
