FILTER_FLOW_SPIKE_FILTER_PERCENTAGE Float R/W
After 'Percent Len' measurements with good quality
have been displayed a new measurement with good
quality is deemed valid and displayed when the
difference between the maximum and minimum of the
present measurement and ('Percent Len' - 1) previous
consecutive measurements is less than the
measurement range (default of 27fps for Flow) times
('Percent' / 100).
