Although not on topic, I think you point highlights a rather unaddressed issue with data and systems relevance. As you imply, not only is it inherently not possible to track a whole population's "wellbeing", doing so in "real-time" is even more ludicrous. So many measures and metrics are really nothing more than utter fabrications that are totally incompatible in spite of being named similarly, and no, that hardly ever seems to dissuade anyone from hooking up to anything but the most obviously egregious offending systems and their garbage data/information.
Just a single aspect of this issue is, what does real-time mean for aggregate, global measures? Days? Hours? Is it somehow more useful to have 100% accuracy at either interval? And what are the criteria that even determine accuracy at all, let alone precision. This is all a kabuki dance with approaching no relevance, especially in the case of the pandemic when there is also approaching zero confidence in the Chinese numbers at all, and it does not matter how many fancy dashboards are put together by "hooking up to such a system", when the numbers could be 2x as high, 5x, 100x, or who knows because they very system of governance and ideology actively evades honesty and responsibility.
ALL of these numbers should be fundamentally caveated every single time any of them are provided with "that they are Chinese data and the Chinese lie about lying, while lying about the fact that they lied. At the very least currently, trusting any Chinese person is an act of insanity, regardless of whether any given individual Chinese person is honest 100% of the time. How much more do people have to be lied to, deceived, cheated, stolen from, plundered, spied on, and infected with communicable diseases that could crash all of civilization by killing millions before we realize there is a mentally ill manic insanity going around that starts with the insanity of not having a common framework for data and information collection, processing, and conveyance.
