I think it should be optional

what other timing would you propose to use?

Time without loads maybe?

That is pretty pointless, as loads are consistent, the only thing it would do is allow 1.0 to be a viable version again, and that would probably make 1.0 the faster version. Additionally, timing loads is super tedious in a game that can't automatically time without loads. It would take the verifier(s) even longer to be able to get through runs.

Im planning to do 100% / AUM but it's too long for me to do it with RTA timing so I think that to do a run like this RTA timing should be optional.

Are you asking to do a segmented run?

they're talking about doing it as a TA, but the run isn't really long enough to warrant TA rules, so IMO it's not neccessary
