So I've been sure for awhile now that it makes difference on your rotation if you hold or force your joints mid air. For example getting into the position of a long stick while spinning will speed you up you will also kinda loose all of that speed after a few seconds. It makes it impossible to do multiple flips in one jump.
Though by holding all in that position this invisible force seems smaller and you can spin noticeably longer.

I just wanted to know if there's any guide, tutorial or explanation on this to better understand it.
