Rates range approx. from 3.33 us to 109 ms. Every iteration is double the previous rate. Once 30 reports are captures, the timestamp delta between reports is expected to be equal to the sample rate. A tolerance of 3 errors in timestamp deltas (in a total of 29 deltas collected) is allowed. A quick repro on APL suggests that the tolerance of 3 error deltas is a magic number. Changing it to 4 increases the tolerance for the mismatches on platforms like APL and allows the test to pass.
