How are the opponent's points (3rd column) calculated in the results of certain tournaments?
For example, in the KohPouTou 2025 tournament

It is the sum of the scores (1st column) of all your 11 opponents you actually played against.

You could go through the 11 players you got matched to, collect their score (1st column), and add up these 11 values. This is your "opponent's points" value (3rd column). The higher the value, the tougher was the pool of opponents you got paired with.

That's right. But I should add one thing: the calculation is done at the end of the last game played. Then the total changes as other games are completed, but your number in the third column only changes if you yourself complete a new game.
