Hey, i'm beginner in speedrun

About the milk method, i heard that there is another method that is easier but slower. can someone explain it to me ( or send a link for a run that are using it ) pls?

(Timestamped) Setting up the green barrel is for a clip that saves like 3.5-4 seconds later, optional You can also do the door glitch to prevent clarence's control effects but that just loses time.

Thx Andy!
