Thanks for comment on that. Not that I am really suspicious, in fact I tend to believe most (if not maybe all) play fair.
This W/Kg info I don't quite get, even if I understand the idea behind it, it makes it possible to compare power output among various riders.
I always thought individual riders in real races or training rides watch their total Watts output on their cyclocomputers (I guess they need to enter their weight in the computer when setting it up), which is typically in hundreds of Watts. Or maybe they have both values on their computer display? It would seem, one should only be interested in those W/Kg either way, on Zwift or real road racing.
I should really look it up on net, probably there is a whole science around it.
I recall article where a pro racer complained he was disconnected (or not counted in a race) when Zwift deemed his power output over their set limit.
