I am very new to Mario speed running, and I am trying the 11 exit category. I was wondering, how much can the cloud glitch and/or orb glitch save time? Because sense I’m new I dont know if I should you use it.

11 exit is divided into 3 subcategories, cloud orb and glitchless, usually new runners start with glitchless, as they do not need a cloud / orb. You can see the glitchless leaderboard using the filter -> 11 exit run type -> glitchless

The orb glitch saves up to 15 seconds over a glitchless run and the cloud glitch saves up to 55 seconds over a glitchless run (however those 55 seconds are incredibly difficult to obtain, hence why less than 35 people have achieved a sub-10 time).
