Hi razmichael, You are correct I did think I had the setting as "Auto" but when I checked it again last night I saw that it was still in the "Barometer" setting, I am starting to think I may not be smart enough for this device :) I will take your advice and try the "Altitude" setting as well as it appears you have a good handle on how this device works best. Thank you for all your assistance, Neil.
OK. If it was set to Barometric mode that would be the issue. Likely you are best in Auto Mode but understand that it will drift - sometimes slowly, sometimes quickly - the watch needs to try to guess what is causing the pressure changes.
