This series was incredibly fun, and timings mattered a lot more than just order, making it very interesting.
In the end, a couple of bad hours lost me the race, but overnight races were the killer. Pretty much every overnight race was an hour lost to Kedy each time, which just added up so much easily.
I think a sliding scale of lateness time loss is probably needed for another game, as the three users who had slower starts were behind after hour 3 and really stood no chance. The rather than losing up to thousands of seconds an hour, maybe cap it at 100s per hour?
First hour after the 1st starts, it's a second per 2 minutes, second and 3rd hour it is a second per 5 minutes, 4th-12th hour it is a second per 10 minutes, and anything after it adds a second per hour.
That way it allows a stinky race to not be the absolute end of your championship challenge.
