Garmin defines the Acute Load as the sum of the Exercise Loads of the past 7 days. It's not hard to calculate, it's a simple sum.
In my case, this doesn't work. For example, the sum of my Exercise Loads as of today is 789, and the watch gives me an Acute Load of 758.
Am I missing something ?...
It's a shame that Garmin doesn't seem to be interested in answering their customers on their own forum. Adding to the frustration.
