The high/low value for daily Body Battery display as well as the according 4-week chart show the lowest value regardless of whether it's been the night before reloading or the evening after a stressful day. With that random mix it is quite useless, does neither show development how much was charged during sleep nor how much was used during the days. This mix of different values before/after highest is misleading and frankly quite useless.
-> Please set to always display either lowest value before or after the highest peak (ideally selectable), but not both whichever is lower.
