Not sure how they calculated those figures but I can't agree with a couple of therm. For instance they say TC sells 1/3 of all MZ's. There is no way in the world that is true. The inexpensive MZ's far outsell TC. Heck I sold them for years. I sold 10 or more cheapies for every TC I sold. No way that number is possible. No way.
The other listings are conceivable, so I am not sure about them. But no way on the TC MZ's. The Pyrodex number suprises me, but I can believe it. WalMart does handle Pyrodex. But you don't see TC's at Wally World. Tom.
