It has nothing to do with size of the jump and everything to do with continuity along the path. A "quantum leap" from A to B implies that the path from A to B was discontinuous and therefore completely unpredictable given the knowledge you had at point A. In other words, You went from A to B without going through any intermediate steps. Said yet another way: B is a post singularity relative to A.
