Identification of Key Points by the “Sextile” Approach Using the FILI Data Distribution From Table 8

	First Key Point—16.66th Percentile	Second Key Point—33.33th Percentile	Third Key Point—50th Percentile or Median	Fourth Key Point—66.66th Percentile	Fifth Key Point—83.33th Percentile	Sixth Key Point—Maximum Value
Key value	0.527	0.672	0.711	0.885	0.960	(FILImax) 1.239
LI category range	0.408–0.526	0.527–0.671	0.672–0.710	0.711–0.884	0.855–0.959	0.960–1.239

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