I am not sure I understand this: There are quite a few threads on regulars complaining they didn't manage to get their watch despite being there, fingers ready, as you open the shop's doors.
This to me says that the current limiting factor (how many you can package and ship in a week) is what limits your revenue, not the fact that a few people may be blocked as there seems to be more than enough of a queue to replace them. But of course I do not have the data that you have.
