How often, across every team and every match we hold — including ones that do not count toward a rating. Advanced stats has a court-position table too, and it answers a different question: how well you do there, over matches that count. A team’s own page shows how that one team uses you.

What matters isn’t how well you play when you’re playing well. What matters is how well you play when you’re playing badly.
