For the person who buys a rifle to hunt deer with, a scope behaving imprecisely during zero is of no consequence. That shooter will get it zeroed and never dick with it again. That's not a failure, since the scope serves its purpose of allowing the shooter to kill deer. Then an internet blowhard comes along and insists that scope is a failure despite the fact that it does exactly what the shooter wants it to do.
20 years ago I was complaining about internet blow hards giving benchrest technique advice to deer hunters.
