A good friend of mine, "Billy Boots", who is a Territorial Governor for several clubs in northeast Texas, shoots with your club on occasion. He shoots Duelist (as I do), and he is both FAST and SAFE, whereas I am only SAFE, but getting less slow. Next time he comes to visit, try to posse up with him, and personally observe what I'm saying.
FAST and SAFE are not mutually exclusive attributes. The safety issues you mention should be reconciled by the stage RO (or whomever is running the timer), since he/she is right there with the shooter, and is supposed to take appropriate action in the event of shooter "brain fart".
The SASS rules for range safety are effective IF understood and enforced by all participants. If you see a safety infraction and don't bring it to the attention of the individual and or RO, shame on you.
