The combinations had numbers up to about 26, Cerio gave them names, Vilari went back to the numbers.
Basically Vilari waited for Cerio to go on vacation to Hawaii, then split from him and promoted himself to 10th degree. Vilari created the rest of the combimation to 108 himself. Many of which are so dreadfully bad and unrealistic, they look like he made them up over the course of a weekend.
I would avoid going to any school affiliated with Vilari. The same can be said for most of the USSD schools as well. Though with those, it really depends on who the instructor is. I have found USSD instructors that were knowledgable about not only the system but also real self defense. I have also come across high ranking USSD instructors that lived in a fantasy world of step through extended lunge punches and thought that was real.
