The native measurement cycle time of a sensor increases with the
stroke length. With extrapolation, the sensor is able to report data
faster than the native cycle time, independent of the stroke length of
the sensor. Without extrapolation, if data is requested faster than the
native cycle time, the last measured value is repeated.

During the measurement cycle, the positions of every magnet on
the sensor are simultaneously reported. The velocity is continuously
calculated based on these changing position values as the magnets
are moved.
