The Mark III, C300 and Red Scarlet in a Nightime Bike Race

In lieu of our recent conversations around what's going to be our next camera, I found this video comparing the low light capabilities of the 5D Mark III, the C300 and the Red Scarlet. Keep in mind that this is far from a perfect test. It seems like giant spot lights were scattered across the track and I can't seem to find any information on the aperture or ISO for the different angles; I assume that it was pretty balanced. I think the best pieces of evidence are toward the end where they are interviewing the biker. What does everyone else think?
