After lots of deliberation with members of the speedrun community I've done an overhaul of the speedrunning system. This does unfortunately mean your times have been wiped, but I promise this is the only time I'll intentionally make a breaking change like this.
I thought it would be fun (and utter overkill) to make an in-game split timer, so here it is!

These times are obviously doctored. Or are they..?
Thanks!
