The only thing I can think of is completely getting rid of getting coins in sphinx room but still get chest, but only top runners would need to go for that because it would save like .5 or a second at most.

Going to snow is actually not faster, but people went to snow first initially because you're automatically hovering over snow when you're given a choice between snow or seaside, allowing you to just mash a and not move the analog stick at all. Seaside was recently discovered to be faster by .3 because certain text will not appear when you go Seaside first. You need almost perfect menuing for Seaside first to be faster however. damn i wrote an essay but hope this helped
