Don't really know where to put this, but I've got a 945 LTE so here we go.
Considering the absolutely huge impact that alcohol consumption seems to have on HRV - would it be an idea to be able to "tag" a day, evening or timeslot with alcohol consumption? Obviously the physical effects are real, and the watch will probably want to act on it with regards to recommendations, but it seems that knowing the reason for a day or two of reduced HRV could still be beneficial to informing the algoritms. For example knowing that a tanked weekly average is due to some drinking in the weekend might mean that some extra rest is good, but not necessarily mean that you are actually overtraining as a trend.
