@krzyśMac Hey, at the moment Resources do not match the phone app, it’s apparently a bug. In my experience sleep tracking was a bit better with Race 1, in my case Race 2 doesn’t recognise waking times (when I go to the toiled during night i.e.), it doesn’t show. The graph you are asking about is fixed, you cannot change it at the moment. Other than that it’s a pretty good watch, just not that advanced compared to Race S/Race 1 at this time. Of course, compared to Race S the display is huge. And I think more features come in the future, but right now I wouldn’t see a reason to upgrade, other than the display.
