inconsistency

Tanaka-sensei took the two new guys and Kanai-bashocho was instructing the two others, leaving me in the back to practice on my own. I went through the five kata for the upcoming national tournament and immediately felt a sharp pain in my right shoulder, just like on Wednesday of last week. So I took it easy and the pain went away, but it made me kind of jumpy, so I was in terrible form all night. In such a situation, I usually just slow down to about one-quarter speed and go through everying in slow motion. I try to exaggerate all the movements, paying attention to one thing like foot position, then repeating again and paying attention to something else like hand movement. Repeating 5-10 times for each form, I slowly speed up to about three-quarters normal speed, now focusing on flow more than individual movements. Doing this I tend to find the parts where I'm doing something unnecessary; hand is out too far, head is bobbing, hips aren't aligned correctly, so I attempt to smooth out the bumps and minimize the extraneous. Out of the corner of my eye I was watching Kanai-bashocho teaching and I realized that I will have a very tough time indeed at the national tournament.
