I'm not about to go down this rabbit hole. You can say what you want, but there is more than enough clearance for a 415, in fact there's enough clearance for a #41 but it typically rubs the case not the cover.The covers are cast aluminum and designed for standard bicycle chains. I'd say that problem is more likely the tolerance of the cover itself. They aren't designed for 415 HD chain.
If you don't know what the problem really is, it's not wise to argue with suggestions of what it could be and probably is!
