What this screen is
What the rally log actually says about how you play: how your points are won, how you do in a fifth game, who you have played and what happened.
Where the numbers come from
Every one of them is worked out from matches that were marked rally by rally. A result somebody typed in afterwards counts towards your record and contributes nothing here, because there is nothing to count.
Head to head
Pick somebody you have played and you get the two of you: matches, games, and how the last few went. It respects what each of you has chosen to make public.
If a number looks wrong
Check the match itself first - the score on the fixture is what everything here is built from. A match still being played is not included, and neither is a walkover: nobody hit a ball.
If there is nothing here
You need a few marked matches before any of this means anything. Until then the screen says so rather than showing an empty chart.
