Precison and recall of a classifier using GPS and ACC data to determine incubation lengths. The interval between each GPS fix and ACC burst was varied along with the duration of each ACC burst. The precision (a) and recall (b) of each resampled data set was compared to the output from the classifer when using the full data set (GPS fix every 15 min and a 3 s ACC burst every 6 min). For the precison plot a break point (black dashed line) is marked, where the ODBA sampling interval is 24 min
