Power loss or gain while ascending or descending. Negative means power gain (descending). When in kcal/h or kJ/h, it also takes efficiency into account.
Power exerted during activity, due to drag forces, altitude change, etc. Negative means power gain, e.g. when going downhill or braking. When in kcal/h or kJ/h, it also takes efficiency and BMR into account.
(All profiles) Recalculate speed from distances, do not use GPS value directly. This may provide more stable speed readings over GPS (Doppler) values. Default is OFF.
