I currently have calculated the averages of each team, and the averages of non-eliminated teams are almost even after two legs, due to a lot of shuffling in placements.
Four teams currently have an average of 5, another two have averages off of 5 by 0.5, and two other teams have averages of 3 and 3.5 (K&R and S&P, respectively).
M&C join a rare club of teams of going from last to depart the second leg, to first in the second leg, and are one of the four teams with average of 5, the others being K&B (who have an EP), A&A, and K&I. Z&S have an average of 5.5, and A&E have a 4.5 average (which really makes you think that their average would be so much higher without the 2 hour penalty).
K&R seem to be the top dogs, but they do have weaknesses. However, they also still hold 2 EPs (one for themselves, the other to coerce a team for aid in the next leg for the EP). S&P seem to be the consistent top pack team (though I see their success landing them short), while Z&S, despite having the lowest average of teams still in the race, are also consistent in being a mid-pack team that could sneak into the top pack later in the race.
