There is a lot of talk about racing and people entering in the wrong categories messing up results. Quite often you will tear your legs off trying to stay in a C cat lead group, only to find when you look at the results on Zwiftpower later, those riders aren’t even registered on there.
If the in game leader board flagged riders who have their account linked to ZP with a small icon that would help to know who you are legitimately racing against with a known category assignment and enforcement by ZP. Zwift already knows which accounts are linked to ZP as that is part of the opt in process to sign up for ZP.
It would also become self policing in a way, as people would see the icon and question why they don’t have it against their name. The more using ZP for racing the better.
