  <p>The number is the <strong>rating change</strong>. Stockfish lost 16 rating point to Houdini, similarly Houdini won 16 points from Stockfish (convince yourself by going to the Houdini vs Stockfish cell).</p>

  <p>For example in the first row and second column, Stockfish vs Houdini, the result is 27-25+7-3=-16. I understand that 27 signifies Stockfish's number of wins+ draws, similarly 25 signifies that of Houdini. But what does "7-3" signify? and how is the result -16? </p>
  
  <p>And what does the blank in Row 1, column 7 mean? similarly in (6,11), (7,1), (7,10), (7, 12), (10,7), (11,6), (11, 12), (12,7), (12,11). Do they signify that those matchups have never happened? If so Where should I look for if I want comparison of such matchups?</p>
  
  <p>This question may be weird, but please at least guide me where should I ask these questions if not the answer.</p>

Comments.Text: A partial answer: The first row in each cell gives the match result in points (1 point for a win, 0.5 for a draw, 0 for a loss), the second row gives the games' results: 7 wins, 3 losses, 40 draws. You should ask the publisher of this table for further details.

Comments.Text: Thanks, you're right. I'm very stupid to not see it. As for the publisher, I tried to make an account in ccrl forum, but the registration captcha is too tough, which I failed 12 times and counting. Any idea why the result of 7 wins 3 losses and 40 draws is -16?
