- Test run number
- Test completion time
- Test completion distance (km/h or mph)
- Maximum speed achieved during a test run (km/h or mph)

If saved successfully, the file name will include the test type, the date and also the time, taken from the first completed run in that session. Along with the test history information described above, the results file also includes average acceleration information, as well as the latitude and longitude position (in degrees and decimal degrees format) added to the session header.
Selecting the Reset Button will reset all test results shown on the current screen. When pressed, the LEDs will briefly flash green twice and the unit will emit an audible confirmation notification.
