Alex (comp_kid_alex) is right that retention should be the focus. At GB, week three of fundamentals is mount escape, and the upa is the first thing we teach. We show the hip bump, then the bridge-and-roll to the knees. But the curriculum doesn't really get into how an opponent reacts when their base is solid. You're taught the move, not the chess match. When I started in 2020, I spent a solid two months just getting hip-bumped back into guard by purple belts who knew exactly what I was trying to do. It’s hard to make those basic escapes work unless you really sell the initial movement.
