How to compute Tie Break?

So how is tie break computed?

So this long tournament has been on going for a while. After I got beaten the first ranker I won my other games so far. I am kind of happy of what is going on until I noticed I have a 0.5 tie break. The leading player has 10.5 which is justifiable. While the 3rd in the list has 3.75 yet he has one draw and one lost. No one else has a score in the tournament at this point.

Is this phenomenon correct?

Yes, that is correct. Tie-breaks are based on your opponent's scores and you have only played one person that has a score.

Oo tama yan kc tinalo ka ng 1 tapos tinalo mo ang 3 at yung sa ibaba na wla pang score kaya 0.5 ang tie break mo kung anu ang score ng tinalo mo !! Mag iiba yan pag nagkatalo na yung mga nasa baba
