Basically I accidentally wrote 4m 31s instead of 4m 42s because I'm an idiot. Idk how to correct my mistake. Does the person reviewing the run change it and accept it even though I was wrong?

You can go to your pending runs and update them.

https://www.speedrun.com/pendingactions should be the link where you can access any pending runs, you can edit them as you wish. You can also edit runs after they've already been verified, however that will put them back into the queue needing to get verified again.

Runs are retimed by mods when verifying them so we'd adjust it if you put in a wrong time, however it makes our job easier if you put in the correct time.
