I think we've been pretty good at naming KPP's. There's one of us naming a KPD that I'm not so sure about but I've been letting it slideI'd wager there's a fair number who don't have their players tagged correctly for keys or not. None of us got the book this year and they ditched the app so we're out of date.
I tended to do a bit of a look to see they weren't taking the mickey, but the last couple of weeks my oppo hasn't had his team on the site so I just take it on trust.
