John, just my 2 cents.

I dont' see you having a 'lock-in' mechanism using the stance shown in the video. I use the GD, so I suppose I'm biased. I did not notice any major head movement, however. What would you say is your 'lock in' mechanism is, something you feel everytime you go from A to B?

A small detail, on a pop up near the plate, don't look for the ball first thing. Locate the catcher and he will take you to the ball.

I know that this was a one man game. My impression was that you felt rushed. When doing solo games, it's important, IMHO, to take your primary responsibility first, that is calling balls/strikes. Don't feel the need to make your calls quickly because you are the only umpire. After all, we are only talking about 1 - 1.5 seconds of delay that only WE percieve, but it makes a big difference in the quality of our strike zone.
