One thing I gained from the class was a practical lesson in how fumbling a grip can make a huge difference in accuracy. Better to get it right, but if it's wrong, don't try and take the shot anyway. Fixing it might cost a couple tenths of a second, but you can't miss fast enough to win...
More dry practice draws are called for, as well as more practice on post-reload and post-malf transitions.
The eyes of a 25 year old pro-baseball player would be great, too.
