"anyone who is coordinated enough to operate an automobile cannot better themselves from a 45/100 score."

If I had to guess, there are a lot of people out there whose driving is 45/100. Another guess is that they guy shooting 45/100 probably would like to improve his shooting more than the 45/100 driver would like to improve his road skills. Personally, I applaud the guy who loves shooting enough to come out week after week and bear his 45 cheerfully.
