LOL - I hear you. DS would never have been tested multiple times by both medical professionals and school psychologists were it not for medical issues. In your DS' case, even the 126 VC is closed enough to the gifted range that he would have not have appeared "behind" in the typical gifted classroom.
I suppose crystallized intelligence versus fluid intelligence is a more accurate way to divide the abilities. However, I believe that while the PR index is far closer to fluid intelligence, it is not purely fluid intelligence and similarly for the VC index.
