   TrainingPeaks WKO+ and the manufacturers' software for the Ergomo,
   Garmin, Polar, PowerTap, and SRM devices.
  * Provides a rich set of analysis tools, including a critical power graph,
   BikeScore calculation, histogram analysis, a best interval finder, and
   a pedal force versus pedal velocity chart, to name just a few.
