I am attempting to speedrun the game (and maybe beat the WR some day), and my runs keep halting relatively early on because of one factor:
I'm trying to utilize the item duplication glitch that many MC speedrunners use, FearfulFerret being the most recognizable. I'm doing it on 1.10.2 (And soon, 1.11) and have gotten the glitch to work before... however, I'm having a lot of trouble doing it consistently. FearfulFerret does a good job of explaining how it works, but never really explains in full how it's executed.
Is there any timing or trick to successfully pulling it off, or any visual/hearable cues?
