There are two 41,000lb delineations in the following link, wake category and weight category. But neither of them is called group II, see page 4/5: https://www.faa.gov/documentlibrary/...der_7360.1.pdf The only “group II” I can find is as discussed above (aircraft design group) which is wingspan and tail height. See page 14 here: https://www.faa.gov/documentLibrary/...ive-201612.pdf
Maybe this is indicative of why it’s taking them such a long time to get FAA approval 
I don’t believe your username. What year did you graduate from Embry Riddle?
