Thanks, Jakester!
I did the L10 run (first) just sort of steady, making sure I saw my front sight, blah blah blah. I didn't scare anyone with my mad, crazy skills, but it was acceptable with no major problems.
On my reshoot in Limited, it was the last stage of the day for me and I was a little tired. The first problem arose when I put two shots on the first target from the holster, when of course it was only supposed to have one. So I had an extra shot on that string. Fortunately the RO and some others reminded me on the second string to make sure I didn't have too many hits on that target, so I put my first shot on the second string into the hard cover so I wouldn't get a FTE, but not have an extra hit. I'm such a gamer!
Then the trouble started on the third string (weak hand only). I have a shoulder injury and if I shoot WHO the same way everyone else does, the gun wobbles around and I miss (or worse!) many of my shots. To compensate for that, I've learned to shoot WHO only with my feet reversed from the way most people do it, so that my strong hand side is leading, and that way my chest muscle can help stablize my shooting arm. That worked like a charm on my Lim-10 run and on both runs on El Prime Minister.
Unfortunately, on my Lim reshoot of Night Moves, I forgot to turn my body to support my shoulder properly. The result was a slow(er than usual) time and three misses to complement my extra shot penalty.
So the short answer is that I made two mental errors, one minor and one significant, that cause me to perform below my ability.
