Just wondering what constitutes a high, medium, or low axis tilt.. Just had mine measured (20 degrees) where do I fit? Also, I didn't get my axis rotation measured, is there a formula to figure it out by using my PAP, Axis Tilt etc etc or do I have to go back and have it measured by my coach?

It is VERY unusual that in this reference, they list tilt of medium as 12 to 16 degrees; YET to measure the tilt using the initial Track diameter (they also fail to use the word "initial"), as you go from 11.0" to 11.5", the degree of tilt goes from 17 degrees to 13 degrees. So the only "medium" tilt releases have a track diameter between roughly 11.25" and 11.6". That seems a little restrictive.
The important part is that they're good as ball park estimates.
Here's another bit of information on Axis Tilt:

I wouldn't say it was any more right or wrong. I'm sure there are more references on the internet.
Getting a flavor for these numbers and ideas is the good thing. Getting an idea how they affect your ball reaction is one key you need to get comfortable with.

For what it's worth, this is from the Bronze Manual:
Axis tilts
• Full Roll (Zero degrees tilt)
• High Roll (3-10 degrees tilt)
• 3/4 Roll (15-25 degrees tilt)
• Low Roll/Spinner (30-45 degrees tilt)
• Helicopter (90 degree tilt)
