When son was 12 yrs old and throwing 65 mph it was hard to convince others that an effective CU velocity was around 58-60 mph. I shot a lot of convincing video proving this but it was impossible to convince unknowledgable coaches. They would place an emphasis on 10 mph drop for all ages regardless of velocity and not 10% which is a major problem when teaching kids to throw a proper CU. A kid who throws fastballs at 60 mph should not drop clear down to 50 mph. The losses become all too apparent in loss of arm speed or motion that tips off good batters.
I never had any luck with changeups at this age either. (We used same arm motion/speed) They were hammered.
