Actually noobsicle´s example isn´t the best. It is easier to flow when you have a slow and almost no-spaced map, snapping is only actually usefull when you have jumps or a considerable distance between notes. Snapping is basically going fast from note to note, and in lineal (non circular) motions. That´s it do not put much thought into it.
That being said, snapping is easier when on higher AR. Cause you´re actually reaching the note when you have to hit, and not before (that fucks up your reading )
