Question for veteran tournament operators: how does pairing work? (Crosspost from BGG)

By Killerardvark, in X-Wing Rules Questions

Any clue how pairing is supposed to work?

Example after round 2:
Player 1 is 2-0 with 10 points (higher tie breaker)
Player 2 is 2-0 with 10 points
Player 3 is 2-0 with 8 points
Player 4 is 1-1 with 5 points (higher tie breaker)
Player 5 is 1-1 with 5 points
Player 6 is 1-1 with 3 points
and so on...

What are the 3 game pairings?
According to the FFG document you go by "point groups" so is (1,2) a point group or is player 3 included in that?

Imagine a larger group now...(assume they are in correct ranking based on tie breakers):
Player 1 is 2-0 with 10 points
Player 2 is 2-0 with 10 points
Player 3 is 2-0 with 10 points
Player 4 is 2-0 with 10 points
Player 5 is 2-0 with 10 points
Player 6 is 1-1 with 5 points
and so on...

Who faces player 6? Who does player 1 face?
Even the FFG tournament document flip flops on this between the explanation paragraph and the example paragraph.

The tournament I was at this past weekend had the following logic.

Round 1: Randomize people. Program simply used a random number generator to give each person a "seed" value.

Round 2: Group people into score groups (there were no ties or modified wins hence my confusion over all that). If odd group, take top player from lower score group and add to bottom of this score group. Then the #1 player using Strength of Schedule and Kill Points tie breaker faces the last player in the group. Repeat top vs bottom until all are paired. Then move down a group. Repeat till everyone paired or player has a bye.

The logic was that the person who was top of the group "earned" the right to face the weakest player in the score group (including the odd man correction).

I don't know what FFG does. But I can tell about swiss-style chess tournaments. It's simpler in X-Wing than chess as there are neither black nor white.

Example after round 2:
Player 1 is 2-0 with 10 points (higher tie breaker)
Player 2 is 2-0 with 10 points
Player 3 is 2-0 with 8 points
Player 4 is 1-1 with 5 points (higher tie breaker)
Player 5 is 1-1 with 5 points
Player 6 is 2-0 with 5 points

1-2

3-4

5-6

Player 3 has to play against someone from the next points group. That's the player with the best ranking from that group.

Imagine a larger group now...(assume they are in correct ranking based on tie breakers):
Player 1 is 2-0 with 10 points
Player 2 is 2-0 with 10 points
Player 3 is 2-0 with 10 points
Player 4 is 2-0 with 10 points
Player 5 is 2-0 with 10 points
Player 6 is 1-1 with 5 points
and so on...

1-4

2-5

3-6

The large group is split into two. The 1st half (1, 2 and 3) plays against the 2nd (4 and 5). One player needs to play against someone from the next group. That's the one at the bottom of the 1st half.

Any clue how pairing is supposed to work?

Example after round 2:

Player 1 is 2-0 with 10 points (higher tie breaker)

Player 2 is 2-0 with 10 points

Player 3 is 2-0 with 8 points

Player 4 is 1-1 with 5 points (higher tie breaker)

Player 5 is 1-1 with 5 points

Player 6 is 2-0 with 5 points

and so on...

How do you get to be 2-0 with only 5 points when a 1-1 could also have 5 points?

Example after round 2:

Player 3 is 2-0 with 8 points

Player 4 is 1-1 with 5 points (higher tie breaker)

Player 5 is 1-1 with 5 points

Player 6 is 1-1 with 3 points

and so on...

Still the same pairings:

1-2

3-4

5-6

1-4

2-5

3-6

That is how one of the paragraphs in the FFG book has it. The other says:

1-5

2-4

3-6 //the odd man out getting the pairing with the next lower group

Blows my mind that a document like that can have immediately consecutive disagreeing paragraphs.

I contacted FFG about their example contradicting their previous text in the document about a month ago. They replied that they appreciated my catching the error and they will be correcting it in the next release.

But.. It gives no TieBreake in the Rounds! Only after the last Round! In the 2. Round..you see the positions from a PointGroup with his Starting number!

First you give all Players a Startnumber.

So maybe Player 1 and 7 and 9 have 10 Points.., the Ranking is the Playernumber! Avter the last Round...you look at the TieBreaker! And if only two player have the same points...you look on there games...have they play a game ...the winner is on the top.. Doesnt they play...you look at the points from the enemy players... This one with the higer enemypoints is on the top!

Player 3 has to play against someone from the next points group. That's the player with the best ranking from that group.

Imagine a larger group now...(assume they are in correct ranking based on tie breakers):

Player 1 is 2-0 with 10 points

Player 2 is 2-0 with 10 points

Player 3 is 2-0 with 10 points

Player 4 is 2-0 with 10 points

Player 5 is 2-0 with 10 points

Player 6 is 1-1 with 5 points

and so on...

1-4

2-5

3-6

1-4

2-3

5-6

Wow, definitely suffered from the "They must know about this, so I won't bother to tell them". Thanks for taking the initiative.

Quexxes - I have discovered the "Start Number" method of sorting. It is very interesting that it goes by this method, but I guess it works.

I dont think so! The last one of a Pointgroup go to the next group! So first you look have you a last GroupPlayer...ok it is the Player5

1-4

2-3

5-6

Consider what I said:
