Took a friend along with my wife for some shooting recently. Just before we left, I suggested some double taps just to liven things up. We started from the ready position at 5 yards. Wife was accurate but slow, so was I, slow but bullets in the proper place about 3" apart. My friend stepped up and almost before I could say "GO" he had shot twice...... but one shot was below the target and the second was above it. Fast is just... fast, nothing more, nothing less.
