Hi,
Using Forerunner 245.
My swimming activity today lasted 35 minutes.
Garmin calculated for this 11 minutes of vigorous activity and zero for moderate.
How did I get from nothing to vigorous without going through moderate for at least part of the time?
Seems unlikely and incorrect.
See screen shot.
I looked at previous activities and they all look similar (although I did find one with a minute of moderate time counted).
