"Promoter Mathew Polley, a third-degree black belt, and Don Turnage, a third-degree black belt under Carlos Machado, are legitimate. White time-in-belt for blue falls a bit short of established norms, that was more than made up in other ranks so not an issue for me. Brown belt is validated by an instructor who I also verified, and black belt promoter operates a different academy but under the same John Machado lineage. Legit black belt promotion!"
