Don, you've done some good work there based on what Gough Thomas suggested. But the responses are indicative of the problem with your system: 1. Most people don't understand it; and 2. Most people think they can find out what you've told them via the "feel" of the gun between their hands. Your system would be helpful if a) Everyone understood it; and b) Dealers had a device with which they could measure those factors and then include them in the descriptions they post on their lists of guns for sale.
But we ain't there yet.
