So bullet spin has had me perplexed also. I've had conversations with my dd PC about wind direction, particularly if it is better to pitch into a wind or not. He said when he asks his students which one would they rather pitch with, most say with the wind. Pretty sure this is the wrong answer if you have a good drop ball since a backwind won't allow the ball to drop as much. Pitching into the wind would make the spin have more effect. I think he agreed with me and it's something I've noticed with dd that when the wind is behind her, hitters have a field day (no pun intended), but there are other times when they just can't hit it because it really drops. She doesn't pitch that fast but her spin is good.
So, wind is something not really talked about in these discussions about movement and in particular rise ball. So one thing that would make a bullet spin rise is a cross wind. That perpendicular force of lift would be independent of the motion towards the plate. So if the cross wind is blowing into a bullet spin and seeing a 6-12 spin then that ball should rise according to the aerodynamics (as long as there aren't any counteracting forces in the perpendicular direction to the plate - with a bullet spin it would only be rotational stability like a football has so nothing counteracting the lift). Problem solved!?!
