What Do Tie Number Tell Us?

In round 5, I saw these tie numbers. What do they mean? Thanks!

i think their the tiebreaker points i've even heard them called bookholes or something but they decide the final winner in place of a tie in actual points you get tiebreaker points depending on which opponents you have faced and how they have faired in the tournament. for eg: if u face X and win, and X wins all his other matches. Then you and the other finalist have a tie in actual points but the other finalist faced Y who lost all his matches you win because of high tiebreaker value

The tie value is the sum of the won games by all the opponents whom you have beaten. If for example in your 2nd game you beat an opponent (call him B) who  won his game in the 1st round, your tie will increase by 1. If in the next round you beat C, who has already won 2 games, you get another 2 points. If in the same round B wins against another player D, this also counts as +1 for you, so the total increase after that round would be +3. If you draw a game, each of you receives half the number of the other´s wins.

Thanks for the clarification

Thanks a lot, Mulligatawney. Got it!
