Worms: Plate

The notion of the worm was inspired by the graphic used for TV election debates. But a Scrabble player's worm goes up or down not on audience reaction, but on wins or losses. For the technically inclined, the height of the worm in round x is the number of wins minus the number of losses, but nudged up or down by the average spread divided by 80. But a simpler viewpoint is that your worm goes up for a win, down for a loss.

If your worm is above the horizontal line, you have won more than half your games.
