I made a "training" map to practice this jump it shows you the correct angle to run @. But since i made that map i learned a new way to do it and can get the jump 60-80% of the time (depending on how big of a rush i am in)
I cant do the jump "on the fly" yet, but when i set up for it i can do it alot.
Also unlike other people who can do this jump I can actually explain how to do it. So, if you wanna learn it hit me up.
