Location will never be turned on nor used during activity, so map will not be available. Data will be acquired exclusively from other sensors where available (Power, Speed, Cadence, Heart rate, Steps, Environment).
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.
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.
