About this app
Belt Level: Mid-purple to low-black. Emphasis: Applying pressure from the top positions as well as from the bottom positions.
This App features 40 minutes of high level information from Professor Roy Harris, a fourth degree black belt in Brazilian Jiu Jitsu, and the instructor of Roy Dean.
The seminar topic is how to create and use pressure in the Brazilian Jiu Jitsu game. Professor Harris was inspired to explore this realm after his training with Rickson Gracie, who felt remarkably different from the other Gracie family members because of his mastery of pressure, and because of the pressure he felt from Rigan Machado and Joe Moreira.
This is an advanced topic, requiring practitioners to have an intermediate skill level in the overall BJJ game.

What we measured

Five-star share of ratings
80–89% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.
