| Â | Lower thresholds | ||
|---|---|---|---|
EMG | Velocity | Force | |
Level 1 | 0.05 | 0 | 0 |
Level 2 – Target for yellow pin | 0.2 | 0.15 | 0.2 |
Level 3 – Target for green pin, breakage for yellow pins | 0.4 | 0.4 | 0.4 |
Level 4 – Target for black pin, breakage for yellow and green pins | 0.65 | 0.75 | 0.75 |
Level 5 – Breakage for all pins | 0.95 | 0.95 | 0.95 |
