After each activity, there is a value in Garmin Connect that shows my estimated sweat loss in milliliters. Today I weighed myself immediately before an activity and immediately after, factored in the amount of water I drank during the activity and calculated my "actual" estimate sweat loss.
Garmin Connect estimated it at ~600 ml while my calculated sweat loss was ~1600 ml. I updated the value in GC.
My question is, will the estimations get better based on my manual updates? E.g., next time I do a run in the same conditions with the same intensity for the same duration, will the estimated sweat loss be closer to 1600 ml, or will it keep giving me the 600 ml estimate. If the latter is the case, is there any way to update the inputs used to the algorithm so that the estimates will be closer to reality?
