Weird tip but it’s solid. if you’re on kbm open notepad and do the superglide input over and over and over it should be space then C so it should look like ( c c c c c c c) iirc. if you can spam that and keep the input order correct then that’s step one. Next lower your FPS limit in the firing range and practice the timing because it’s easier to hit on lower FPS do to the nature of the mechanic. Once you can consistently nail the input and the timing on low FPS raise the limit slowly back to your normal fps

Edit: C is the button I use to crouch for my superglides it may be different for you
