Nope, I just gave up rather than let them replace the watch a second time!
From my observations, the problem is not the barometric readings as when I look at a spot elevation at a known altitude such as the top of a mountain the value is near perfect. I believe the problem is the algorithm that works out total climb.
Same here, the barometric reading is mostly fine for me. I use smart recording as every second recording make thinks worse.My problem is that the barometric reading stop working during activity (not always though), but if I press stop/start it start working again. This means it's most likely a software issue.
