It's because you UK guys use the metric system (obviously).
Why is the Leaderboard count of a team different from the highest rated Daily Match players count?

You didn't understand the question, I guess.

I told you it is filtered. If you check those forums about the club redesign it’s in there somewhere. By activity somehow. People who’ve played or finished games in the last x days. 90 I think. But guessing I can’t remember and I’m not looking through all those forums you can do that.

It was when we had no list of players by rating we were told to use the club leaderboard and discovered it was filtered. Players by rating has now returned.
The leaderboard of Elite Chess Team shows 23 players with over 2000 ratings, but the highest-rated daily match players menu shows we have 47 players with over 2000 ratings.
