A bike used in a normal way shouldn't need that much alignment if you need that much alignment my guess is your derailleur is out of whack or you have done something wrong or just don't know how to use the hanger alignment tool (which is not uncommon). I know why I would make a claim that a bike used in a normal way shouldn't need a bunch of alignment because it is true. I work in and own a shop so I know that we rarely need to adjust hangers on normally used bikes. I don't know why you keep having these problems but I am guessing there is some issue in your training or you have some customers who are really bad with their bikes or you are selling some really cheap stuff that most shops wouldn't sell because it is so problematic.
