If you take that as a live counter of the number of subscribers that's 2k a year, and pretty good!
If you take that lifetime registrations that's not so good.

Very true, also for Austria. When I was in the military and we got our Steyr AUG A1 we had to know the serial number by heart so we could find our gun when mixed up. We also had to report our serial number when asked by instructors. Mine started with "HJ18" which was by random chance but always wondered why these wouldn't be taken out before production because of the obvious nazi code
