+|movingtostaticratio                                          | -   |  Ratio between stationary time and total location sensed time. A lat/long coordinate pair is labelled as stationary if it’s speed (distance/time) to the next coordinate pair is less than 1km/hr. A higher value represents a more stationary routine. These times are computed by multiplying the number of rows by `[SAMPLING_FREQUENCY]`
+|outlierstimepercent                                          | -   | Ratio between the time spent in non-significant clusters divided by the time spent in all clusters (total location sensed time). A higher value represents more time spent in non-significant clusters. These times are computed by multiplying the number of rows by `[SAMPLING_FREQUENCY]`
