So why is this "wrongly" called a compound radius when that's the only term I've ever seen applied, it is used as the standard terminology in the industry, and it follows one of the multiple meanings of the word "compound?"It is essential that a progressive radius (wrongly called compound) is maintained, leading to a flatter radius at the bridge, being not just allowed but required for proper set up.
Ergo, a 9.5-14" radius would need about a 16" radius at the bridge. A 10–16" neck would need somewhere around an 18" radius at the bridge.

Another perfect example of this is the use of the term "tremolo".Just because a term is in general usage or the only term you have seen does not mean that it is technically or mathematically correct.
In what way? Tremolo is rapid variation in either pitch or amplitude. When has it been used outside of those definitions?Another perfect example of this is the use of the term "tremolo".
Starting with the Year 2020 model, the radius profile of the Ultra changed to 10" - 14".its not worth the upcharge IMO so I would stick with 10-16. If you want to feel 9.5-14 and make your own judgement, any American deluxe American elite or ultra after 2010 has a 9.5-14 compound.
