CCM overall seems comparatively much easier than DDD and fire sea in the 120 star route, so why don't runners do it as the last stage before upstairs? From my (imprecise) estimations this only seems to be at most 1 second slower than the current route, but gets two of the hardest stages out of the way significantly quicker.

I'm not sure if this has already been found or not, but I have an idea for an alternative backup strat in HMC 100 that I haven't seen any top runners use. Here's a video i quickly made that attempts to explain it:

Could this be viable or am I missing something? I don't have a super good knowledge of the route so I'm not sure.
