Yeah, I was going for something more smooth, it’s always awkward when the speed just jumps from normal to something else.
Also, a problem I have with your method is when I’m adjusting the speed of the keyframe in the middle (B) there’s no way to make it have the same speed on both sides. If I speed up from A to B it slows the speed between B and C, as if there’s no way to keep a consistent speed between A and C.
