As noted in the Ranking the Teams thread, we had a very unusual pattern emerge beginning with leg 5 through 11; starting with leg 5, the average placement order of the remaining teams after each leg did not change; in fact, no matter the order of finish, the average placements of the final three teams won't change.
I started computing trends during the season around TAR 10 or so, and this is the first time I've ever seen this particular pattern. It's that unusual.
