I'm a long time user of VA watches. I've started with first generation of VA watch, two years back switched to VA3 and now, since two weeks I'm using the latest VA4. I was very happy with the previous generations, but this new watch is quite disappointing due to some inaccurate statistics.
The main problem is the number of recorded floors. The watch is adding floors while walking on flat terrain (could be more than 10 floors while walking along a 500m flat area). It's quite weird that this behavior is not always happening... same day, same weather conditions, sometimes it records new floors, sometimes not.
Searching the forum I've seen a few similar remarks. Have you found any solution for this? Is the problem appearing continuously for you? Do you think it might be related to the current SW (5.10 in my case)
Besides that I've noticed a few other differences compared to VA3. Resting hear rate is sometimes inaccurate. There are some sudden drops of the hear rate during the day (today went down to 44), and the resting heart rate adjusts to this value (although throughout the night was calculated as being in the 50 range). Such scenario happened already 2-3 times since I have the watch, I think it's a misbehavior.
The deep sleep period is shorter compared to what VA3 was recording, sometimes no deep sleep period at all (was never the case for VA3).
I'm still having the option to return the watch and still use VA3 , which was much more accurate (especially when it comes to floors count). So, any experience from your side would help me take a decision.
