I do not particularly like it when players are tied on match points for first place, especially when the MOV varies so much between Round 1 and Round 4. I had an idea I thought I would throw out there for for a possible 5th round if you had more than 16 players and 2 or more undefeated.
Basically Round 5, take the ships and upgrades for the last 150 point round, and build a new list at 100 points. This should make people think a bit because what the build for the 90 and 120 point rounds will not likely optimize well at 100.
