The pairings for your round were as expected (as I expected anyway!). When using swiss pairings, groups are always created from the top down. In other words, the group three- or two-player group will always be placed at the end. So it makes total sense that it would be 5x/5x/8x in the first group.
I’m sorry for the inability to move players between groups. I forgot that in knockout tournaments there are legitimate reasons why a group may end up with only two players.
Send me a link to the dummy player and I’ll exclude those results from the ratings. Open your tournament on MP Live, click the dummy player’s name in the tournament standings and send me that URL at email@example.com
@Law is correct about the tournament standings. While strikes are used to determine when a player is eliminated from the tournament, the number of wins determines the tournament standings. If you adjust strikes, you may have to move things around a bit before submitting to IFPA.
