"Blame the IBJJF when, in 30 years you see an academy that nails the phrase, "A Red belt is a Junior black belt that hasn't died yet" on the far wall."
I've taken it a couple times in the past, about 13 years ago I got ENTJ, although each one was just barely over the line. I took it again about 10 years after that and was more strongly ENTJ.
