ozzylan-i responded to that question on the page of the video where u commented on it. i hope it helps!
K1LL-yes, it does. most glitches would not be possible because of it. and i dont quite know why it makes u jump farther...but it does. and if you wanna get big in glitching you should practice this a lot.
again thanks for the feedback everyone! try to post this on a few other sites aswell. thanks.
