This has been known for a while, but I'm posting it here just for anyone to see. When you save reset you clear the first firebar sooner but have to wait for the 2nd firebar anyway. Without save resetting you wait on the first one but catch the same cycle on the 2nd firebar, essentially gaining time by not save resetting. Saves 0.9 to 1 second.
Wasn't sure what your visual is, so I've added a setup. Can't wait to get stuck in the wall with these strats from rushing the damn thing.
I have shared this with Anso and eelusion, and it was eelusion who came up with a really good setup but so far Anso is the one who's using it. You can look at what Anso does in his latest PB, might be a better setup.
Tough decision, honestly. It adds an extra 6s of time loss if you skip the save, but saving there is terribly distracting and the spike jump is easy. A matter of preference, I suppose.
