One assumes that nobody waved a magic wand and decreed «let there be MMTS» there must have been an
adoption R&R process where the new sensors were validated against the old across the full
range of temperatures, seasons and sub-climates; in the presence of a calibrated third instrument more precise than both candidates; with data collected to
estimate the error in the instrument, the error in the measurement process, drift rates and recalibration intervals.
The study did not assume 100 %
adoption of each intervention; rather, drawing on empirical data of
adoption rates for previous health and environmental behavior interventions, the researchers
estimated potential
adoption rates
ranging from 15 % for carpooling to 90 % for weatherization.
