On Garmin 965, It would very helpful if we can see our Estimate Sweat Loss at our wrist on Training Data Field while we still doing the training, not after we finished training at Activity Result on Connect app. By looking at our ESL (est sweat loss) we can drink to replenish liquid loss on real time, on watch face. Not after the training. Just like we can see Calories burned and Stamina on real time, not after. At Data Field, At Glance and an option at Watch Face.
