The reason it ends so early is that a major sponsor is Harpoon brewery, and they want the awards ceremony to coincide with the start of their Octoberfest. OTW needs at least a week to compile all the late results, and have the winning team's name engraved on the brass square that's attached to the base of the Cup.
I mean--what would the awards ceremony be without the oompah band and free beer.
You want the winning team to drink Pepsi from the Cup?
