Here’s what I think is going on:

-Each Peen is given a certain value based on the number of people who have it. The more people who have a Peen, the less it is worth.

-All of a player’s Peens are then added together to form a hidden score.

-Everyone on the site is then ranked based on their scores. The person at the top gets 13 inches, and the person at the bottom is given 0 inches. Tied scores get the same lengths.

-It is easier to advance near the bottom because so many low-level players have the same set of Peens. If you get more than those, you are already ahead of all of them.
