Further refinement given the specified interval 26.6Kmi:
92.2/26.6 = 3.5 intervals.
(If an allowable wear rate is Range/Interval, .06mm/26.6Kmi = .0023mm/Kmi)
1.9 - 1.78 = .12, (2x range/3.5 intervals), 57% allowable wear rate
1.9 - 1.82 = .08, (1.3/3.5), 38%
1.88 - 1.85 = .03, (.5/3.5), 14%
1.88 - 1.82 = .06, (1/3.5), 28%
If you were close to the bottom of the range but did not change, should it be OK if they get as low as .22-.06 = .16mm by the next interval? Maybe beyond that is pushing your luck??
Note: I admit I got up too early this morning...
