Fast as greased lightnin' is not how I would characterize the 85 th percentile shooter. If you are a gunfighter, obviously you should know your trade. If you can't get 4-5 hours practice everyday with your sixgun, and you aren't hugely talented in the first place, you're probably not going to beat a super star. I'd advise against laughing at the other guy's mule, just to err on the side of caution. There is the Judge Roy Bean approach to defeating quick draw artists, but the legal implications are enormous, unless you are in fact the judge.
