I would say the guy is lying unless he is counting hits on a youtube video. His claim is like the sports stars who claim they had X amount of girlfriends, to accomplish what they claim they wouldn't have time to play sports.
It would be anybody's guess about the number of new wood bows out there, some guys are very prolific. I have made around 160, I know a guy who has made thousands and another guy (now deceased) who claimed to have made 10,000 bows and probably did. Guy #2 had milling machines set up to shape his bows, he would run a bow through the machines, string it and do a rough tiller on a balloon sander then pull the bow to 31", if it didn't break he shipped it. Total time start to finish; about 15 minutes, I was in his shop one time and watched him crank them out.
