when I did it : only 15 hours of flight training and half of the ground school hours , 1 flight test, still despite my 700 hrs instructing I was issued a restricetd FI for the next 100hrs instructing.
no credit to be FI instrument and me , I had to do the 5 hours for ifr and 5 hours for me plus the 2 flight tests, this after the 100 hrs.
