In real life, I'm a statistician, but I've been coaching and judging men's gymnastics for nearly 40 years. These days, I coach competitive trampoline, but I still keep up with judging in the men's program. Every 4 years (after the Olympics), the powers make us empty the old rules out of our heads, and pour the new ones in. I actually used to photocopy the code of points and slice it up to make a physical set of flash cards. I'm hoping this makes the task a little easier.
