Intermediate Calculations for VLI Example in Table 1

	LI Categories
Data Category	0.3–0.67	0.68–1.0	1.1–1.4	1.5–1. 8	1.9–2.1	2.2–2.5
Representative FILI within category	0.44	0.90	1.29	1.64	2.0	2.5
Number of tasks in each category	8	3	7	5	1	1
Percentage of tasks	32%	12%	28%	20%	4%	4%
Frequency (lifts/min)	0.96	0.36	0.84	0.60	0.12	0.12
Reordered by decreasing FILI value (highest = 1)	6	5	4	3	2	1

Note. FILI = Frequency Independent Lift Index; LI = lifting index; VLI = Variable Lifting Index.
