what do you mean resigned? Doesn't he teach instructors any longer as he used to do? Jorgen is one of PAT creators along with Ralph Eckert, and these two are European pocket billiards federation head coaches (instructors). So what exactly resignation do you mean?
As for PAT testing, I believe every PAT instructor is entitled to run it. There is a set of shots to be made (average of 3 attempts calculated) and positions to be run. Then you get your score and see what level it matches.
Pretty nice comparative system. Though I know some people who play better than they perform the test. Must be gambling nature of those people, lol.
