It is based on the same back end but the data is not always the same.
For example, if I use the Garmin Dive app and set the SAC for a dive to 1.1 bar/min. When I look at it in Garmin Connect the SAC shows as 1 bar/min (which is meaningless).
The more I think about it, I think calculating SAC is meaningless. Aren't you comparing air consumption during some sort of activity on the surface with the activity at whatever pressure you are diving to and trying to come up with how much dive time you have left? If so it sounds like apples and oranges to me. Convince me otherwise. The Garmin video says that it calculates air / dive time remaining. However it does it I think it might be interesting to see if it is accurate. It does not bother me one way or the other; I have yet to come up with less then 800 to 1000 psi in my tank when everyone else is drained.
