Formula

Work total = sets*reps*work; Recovery total = sets*(reps-1)*rest+(sets-1)*set_rest; Work fraction = 100*sets*reps*work/(sets*reps*work+sets*(reps-1)*rest+(sets-1)*set_rest)

Worked example

Inputs

Sets: 4 sets
Reps: 6 intervals/set
Work: 30 s
Rest: 20 s
Set rest: 120 s

Expected results

Work total: 720 s
Recovery total: 760 s
Work fraction: 48.64864865 %

  "set_rest": 120
}

Accuracy and scope

No recovery after the final interval in each set beyond the specified set rest. Not an exercise prescription.
