Typical specifications are not guaranteed.

Guaranteed by design.

The period (1/ODR), length of time between two consecutive sampling, must be derived by the reciprocal of the maximum.

and minimum ODR limits: for example for ODR = 189.4 Hz, sampling period range will be within [4591

μs, 6211 μs] (where

ODR minimum and maximum have been approximated at 162 Hz, 219 Hz respectively).
