The highest altitude is the maximum value of the altitude value per unit time during the exercise;
The average altitude is the average value obtained by accumulating and dividing the altitude values of each unit time during the movement;
The cumulative rise/fall is the accumulation of the cumulative upward/downward data during the exercise. Take the cumulative rise as an example. For example, when riding, there are 5 uphills on flat ground. After climbing each slope, the altitude will increase by 8 meters. Then The cumulative rise after climbing these 5 slopes is 5x8=40m (the same is true for the cumulative decline, and the cumulative height difference of the slopes is summed).
