01
Tap immediately when pressure feels sharp - muscle damage accumulates faster than pain.
02
Calf cranks feel like discomfort rather than joint danger - leads to delayed tapping.
03
Never attempt explosive escape or straightening leg while wedge is locked.
04
Not recommended for white belts to apply - requires skilled progressive pressure.
05
Training partners must apply gradually and release immediately on tap signal.
