The Problem With All Endings
Whenever someone speedruns all endings, and a newer version releases (that features more endings) the older speedruns become obselete/get a new category, But this could be solved with this speedrun category idea.
Max%
In Max%, you need to get as many endings as possible, BUT if a newer version releases then a person who got more endings then you will get the number one spot. The endings come BEFORE the time needed to get them.
Example
let's say you just did a speedrun which got 18 endings in a time of 10 minutes, and then a new update releases which has 19 endings, if another person does a 19 endings speedrun in 30 minutes, then he will be first place.
Let me know if I missed possible issues that can happen with this category or you don't understand the category.
