Minecraft – How to pull off the item duplication glitch consistently

minecraft-java-edition

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?

FearfulFerret specifically uses an older version of minecraft solely because it's easy to use the dupe glitch. If you want to dupe items consistantly, you can change your minecraft version to the on FearfulFerret uses by changing your profile settings in the launcher. Even if you aren't using the most recent version of minecraft, as long as you aren't using cheats/mods, the speedrun still is valid.
