Rick, you'll understand this or be able to explain it better than me but...we often talk about a typical fastball having a 1 to 7 spin as seen from both above the ball or from the catcher's perspective. As the spin starts moving to a 2 to 8 you can see that the clock reference on axis spin direction only works when imagining the axis from above. A bullet spin is 3 to 9 axis when seen from above as the ball moves through space. But, when talking about a curve axis you'll have to switch the clock reference back to the catcher's perspective again. I would think a RH pitcher is looking for a 10 to 4 axis as seen from the catcher's perspective and when seen or imagined from above you see the clock reference doesn't work. I think I'm over thinking but seems to be true.

Out of curiosity, what would you expect for the spin orientation of a drop ball? I expect pretty much the same spin orientation.
Actually, depending on the situation more often than not I would take the 1-7/22 over the 6-12/18-20.
I'm betting some smart math guy could come up with an equation that factors: RPS, Axis and MPH on a given pitch for effectiveness. Even mph has an effect on movement for a given RPS and axis orientation. If a pitch is 22rps and traveling 60mph and a 12 to 6 spin axis it will have a predictable drop providing the release angle stays consistent. If she hits 65mph and everything else stays the same then the movement will be less yet reaction time for the batter will decrease. Maybe a net gain of zero for either pitch against the other. I caught a PC back in the nineties who only threw about 55mph but could spin that ball like no other. Had his the spin rate stayed the same but increased his speed to 65mph, I imagine those different pitches would have flattened out considerably. I'll never forget an old Nolan Ryan adage: Good hitting is about timing, good pitching is about destroying that timing. Vary the speed, change planes, location location location.
I think a 12 to 6 is ideal just like a 6 to 12 is ideal for a riseball. If a girl is hitting 1 to 7 on her fastball and she's hitting somewhere around 20rps I'm sure she's getting good movement and her FB is now her DB.
FFS, I certainly don't claim to be a pitcher, I know I'm not. I also know I'm not even remotely in the class as a PC with many serial posters on this board. That being said, Rick Pauly has a pretty good video on how to throw a drop ball. I can throw a nice 18rps 1 to 7 fastball with a super sharp stripe, no wiggle, 52 mph tops. Watching Rick's video I learned that at plant, if I hinge my waist and lean forward slightly at release--my stripe will go to a pure 12 to 6. It can be done. I tried to get my number one to try it but, we're just too late in the game for her. The 1 to 7 is more than effective and our time is better spent elsewhere.
