- Hi, despite the information received from @Garminsierra that the bug was 'probably' fixed in 18.20, I have to say that today I had a run after a couple of weeks of recovery after a flu and I was running with +30sec X minute slower than my normal pace and HR was around 140 BPM. All of a sudden, out of the blue, without changing my pace despite the very relaxed feeling, HR jumped at 185bpm, that's also exceeding my max HR possible for my age and my training level. I had to deactivate WHR and switching it on immediately after to get it working properly. After further 10 minutes same situation. Now, the thing is, i could also accept this and just don't care about that obvious bug, if not that all statistics are very much dependant by HR. I'm referring to vo2max, performance condition, rest hours, endurance score, suggested daily training etc etc...well Garmin, I'm sure you know that's probably the BIGGEST bug ever since here the whole reliability of the watch is under discussion. this is a sport Watch, probably the best out there, but if HR is not working properly, well, we're far from being an entry level watch. Furthermore, a friend of mine was running with a 69€ watch and HR was just perfect, consistent, stable and reliable.
