Yesterday, I played advanced gunnery. It ends with all the enemy ship destroyed and me keeping just a raider: 481 to me, 466 to my friend. No problem but we thought about it.
If my friend would choose the cr90 as his objective ship, I would score 444 while he would score 466 (my objective ship was my ISD) but as long as:
"One Player Defeated: At the end of the current game round, all of one player’s ships are destroyed. The player with at least one ship remaining earns a win and the opposing player receives a loss. The players determine their scores."
I win, he looses but:
"Since margin of victory is used as a tiebreaker, each player’s cumulative margin of victory must be tracked during the tournament. The winner adds the match’s margin of victory to his or her cumulative margin of victory; the loser’s cumulative margin of victory does not change."
What happens? Do I earn -22 points? The only thing we could figured out is the the looser doesn't change his margin of victory (as the rule says) and the winner get 0 (just a thought cause we didn't find anything to defend it).
