I understand what they are doing, as I looked into it. You get with a partner and work the techniques and spar together. You get your strips by distance video evaluation, but the belts are in person. Frankly it appears very well thought out, as they explained it for an hour. The program actually seemed to address a problem that exists in schools, that of the uneven grappler. In their program you would have to be good at guard, clinch, top, transitions, etc to pass. You couldn't just master a certain gym strategy and beat everyone hiding really week skills in one area.
My only problem was I just don't care to for gis or belts, but that is me, not them. They had some video students and they looked sharp. My only concern is the sparing as you need partners, but if the belts are done in person, then weak sparing would be addressed at that time.
