Two things I think need to be addressed, especially for the any% category: the inclusion of loads, and the timing standards (which Gelly brought up originally)
In my opinion, RMME should be timed from the moment the player gains control on the docks, to the moment the white page appears in Atrus' hand. Both of these moments can be selected frame-perfectly.
Furthermore, any frame in which a load bar is visible should be untimed. Livesplit might be able to do this automatically.
Neither of these seem very difficult to implement, even retroactively. Opinions?
