I suggest some slight changes to run timing conventions and definitions. I've edited this guide to my proposal: https://www.speedrun.com/sotn/guide/eho60
This includes a change in how we define loadless timing to better suit how we do it. Instead of defining the loading period, I think it is better to define the gameplay segments.
I've made a tool that can hopefully help make the process of timing runs with or without loads less cumbersome: Segmented Timer
Additionally I think it makes sense to round milliseconds to the second decimal point since encoding and capture methods make the thousands effectively meaningless.
I agree completely with the change to round away milliseconds, although this only affects Maria runs, correct? Would we need to retime already existing Maria runs (wouldn't be a gigantic ordeal, since it's a smaller category) or would this only be in effect moving forward?
Well no everything that has milliseconds should be rounded to hundredths is what I'm saying. No need to retime.
