I have read through the X-Wing tournament rules and found them to be very confusing, particularly in the Seeding section.
First off, " Standard Swiss style pairings are used (see FFG Organized Play support page for details)." I have found no such documentation on swiss style pairings in the FFG support page. There are many variants of pairings in swiss style tournaments, and FFG's rules explain three of them.
Score Group
FFG Does not define what a "Score Group" is. In normal swiss tournaments this is the points you win by playing, 1.0 point for a win, 0.5 for a tie and 0 for a loss. FFG gives tournament points at the end of a match worth 5, 3, 1 and 0 points - which is mentioned after the Seeding section. I think FFG means win points, since their document says, "s ort the players in each score group by player number, then pair the top number to the bottom, the second to the second to last and so on. This allows for the subtle adjustment of players if one player has already played another player and has the same effect as using brackets so that the top 2 players do not meet until the last round. "
Let's assume that I have 8 players and the results of the first round matches are 5:0, 5:0, 3:0 and 3:0. Players 1 and 2 each scored 5 tournament points and players 3 and 4 scored 3, though all four have scored 1 win point.
(1) If I seed by tournament points, then my two best players so far will face each other in round two, which is in conflict with the underlined text above.
(2) If I seed using win points and " pair the top number to the bottom, the second to the second to last" then 1 plays 4 and 2 plays 3.
(3) The example listed in the document says 1 should play 3 and 2 should play 4, so now we have three was to pair that FFG has presented in the section.
When I look up swiss pairing in wikipedia it says to use option (3).
Breaking Ties
This section says to first combine opponents' match points. Is this win points or tournament points?
The only time tournament points is mentioned is in the championship bracket formation. As others have pointed out, you can have a higher tournament points going 2-0-1 (5,5,0) than 3-0-0 (3,3,3).
Does anyone else find this confusing?
My local store has used the Wizards of the Coast M:tg tournament sytem for all swiss tournaments. It pairs players based on method (3) and then sorts them by strength of schedule. Any tournaments I run will not have a championship bracket, so it appears that I don't have to keep track of tournament points.
