off topic
60-130 sounded reasonable to me because that is about what two cars on the highway might get in a quick race (if they slowed down a bit at the beginning to have more of a race)
However, from looking at the MB thread, they don't actually start at 60 and punch it, like they would in an actual short highway race. They punch it at 25 or so and then subtract the time taken to get to 60 from that taken to get to 130.

So they are actually racing from 25-130 but only counting the 60-130 part, which is not any race at all, is purely numbers-only, and makes the 60 starting point even more arbitrary (since it isn't for highway racing since they don't actually floor it at 60).
I could just about assume this was started by a car group that had a shift right before the 60mph marker, and so favored their car (they probably also shift right after 130). Even better, for the C5 or C6 Vette, which is the standard "fast" car around most areas, they hit slightly over 60mph in 1st gear, so they get an extra shift right at the beginning. I smell intentional BS in the 60-130, whereas I initially liked the idea.
