Well arithmetic allows a better time than that, just by taking mine or pirahpac's best laps and doing that 5 times. Then he may have mastered the double barrel roll on the long left. You can do 3 on that corner as well, but it's hard and I never tried to make it work properly so don't know if it's fast, probably not. I think the track also has certain subtleties that could be changed, despite being counter intuitive. Whether any of them offers a faster method I don't know, I'm not good enough to be one of the pioneers like that.

If he used Fury Icaras then that would definitely give a slight edge, based on my experimentation with it. Ultimately, Elois can be crazy consistent, so it doesn't surprise me too much, whatever ship he used.
