Here is what you should do. This is just my opinion but i believe it to be fair.
Take Raiders largest lead by his count. Then take Shack's smallest defecit by his count, split the difference. I believe that would leave raiders with a 4 or so unit lead. Then bring in someone impartial like Big Ragu who has already voluntered his services. Go by his rules and let him judge this contest for one week without bitching and crying. Then all Sea would have to do is hold the money until someone wins. Best man wins and problem solved.
