I have the average rates and can post them too if that might help:
Average spin rate: 1861; Average IVB: 19.2; Average HM: -5
Actually the great thing about the data and Bauer units specifically is that it is relevant not just for top-level MLB velo and spin rates. What the Bauer units can do is adjust the spin rate comparison for lower velos (like in hs ball).
Here's a good explanation:

Here's from the conclusion to that article: "For pitch development, Bauer Units can help determine how a younger pitcher can best use his fastball. They are interesting to know for offspeed pitches, but knowing an offspeed pitcher’s Bauer Unit doesn’t directly benefit pitch development. In the end, Bauer Units are going to be most useful for coaches who deal with pitchers who don’t throw at elite velocities, such as high school and some college pitchers. It will normalize spin rate so you can understand if your pitchers have an average, above average, or below average spin rate, which will affect how your pitchers can utilize their fastballs."
