The entire Gracie Barra model is textbook mcdojo. But the quality of instruction is pretty darn high.
Everyone's got their own definition of a McDojo, but most will agree that a place where "...the quality of the instruction is pretty darn high" isn't one of them.
Low quality instruction and/or unrealistic techniques is pretty much universally accepted as the first criteria. Most often accompanied by high fees.
If Royce Gracie or any of the other Gracies charged $500/month to train with them personally and they were turning the student(s) into BJJ machines, I wouldn't consider it McDojo. If they charged $100/month and taught absurdity, I'd consider it classic McDojo.
