If you practice martial arts, you know exactly what level your sparing partner is by his or her belt. I think we should have a belt system for turners. Or maybe a Smock System, because you don't want a floppy belt getting caught in your lathe.
I thought of a couple. Help me out here.
Clean Smock - never turned on the lathe. The lathe is still shiny, too.
Yellow Smock - from what happens when you experience your first catch.
Brown Smock - from what happens when a catch explodes a bowl.
Red Smock - from the first through the hundredth time you realize that if you can't see part of a spinning object, it is because it is a corner waiting to slice your fingers.
Spotted Smock - from every time you applied a finish on a piece while it is spinning.
