In the limit this is 15.077 CA per Vitae and was much easier to figure out than a clean 15 CA/Vitae. After week 1, I'm sure even better than this is possible even though I don't see how.

(some further working out that you don't need to read aloud)

A 15 CA/Vitae with >= 4 arms is not possible as it takes 4 cycles per vitae minimally.

A 15 CA/Vitae with 3 arms, when accounting for latency, ends up scoring 1179.
I don't believe a 12 CA/Vitae with 3 arms is possible, but maybe there is some really weird setup to get between those.

A <= 15 CA/Vitae with 2 arms, i believe, requires grabbing a Vitae/Mors with (almost) every Salt, which I don't think is possible.

With 1 arm, there are only so many ways to lay out the track. Using a bonder instead of disposal allows for 4 tracks, but I couldn't do better than 15.077 CA/Vitae (and was 1 slower on latency and much larger area).
