A plot of messiness of a board versus time. There are three regimes. The first (the steepest) is for someone that rewrites equations constantly and erases the board with their fingers. The second (moderate steepness) is for someone who has trouble erasing well. And the third (the shallow slope) is for someone with very clean writing.

There are many other variations. See Board Work.
