-Smoothed signals are calculated using a simple 3 week moving average of the relevant weekly signals. Note that since the unsmoothed `pct_visits_*` signals report weekly data, each smoothed signal value is computed from 3 points rather than 21, as would be used if the unsmoothed data were reported daily.
