22 2 × (1–10) repetitions 0–20 0
24 4 × (1–10) repetitions 24–60 20
26 6 × (1–10) repetitions 66–120 60
28 8 × (1–10) repetitions 128–200 120
30 10 × (1–10) repetitions 210–300 200

aThe added score is equivalent to 10 repetitions of the levels below that of the current activation score. The total score therefore includes all attempts at all activation scores achieved.
