I think you put wrong video in the wrong chapter

Would reloading checkpoints to skip cutscenes be allowed? in the any% (submitted ones), they skip one part @ 50 secs by reloading the checkpoint. (you can see the video ran by Deln) But he doesn't do it later in the game? is it allowed or does the runners just not know about them?

i wanna know if i can or will it be classified as a diff category?

also i why i am at it to know the rules about quick load and quick save? cause in this game it can unload parts of a level.
