I guess maybe their bubble has popped?

Skill sets are interesting. Not to get off topic but I have flown radio controlled airplanes for many years. We had a local based commercial pilot coming to the flying field. He could rattle off all of the "numbers" such as V1, VR, etc, knew all of the languge. But after crashing 5 different airplanes over the course of several months, we never saw him out there again.
He was a high time pilot certifed in B-727-100, B-727-200, DC-9 (all variants), MD-80 (many variants), MD-90 and B-757 & B-767 which are basically the same flying platform with a few parameter differences.
I relate grading to flying R/C in that you must develop a feel for where your machine is at all times.
