Just to flog a dead horse some more:
Supposing you goofed and for whatever reason you backclipped and knew it. What is the best way to deal with it: leave it be and try not to fall, unclip the rope and do it right, or rotate the biner?
I suppose the answer would depend on the situation. If it was the second bolt, I'd take the time to get it right. If the last one, I'd blow it off.
