Yes, well, we also have double points week, which automatically results in a 50% variance. And your lowest weekly will be dropped. So yes, not all weeks are the same in that regard.
I did the same thing two years ago when the Wofford/Stanford game was canceled due to poor air quality. Max points was set at 15 points. Nobody had any issues with it then. If my scoring system went 6-5-4-3, in the event of two games being canceled, it would do the exact opposite of what I've done in all other cases. I've always taken from the top - whether a game is canceled, or whether you're late. Scores have been dependent on how many games are played.
The picks above are the perfect example of why I think taking from the top makes more sense.
From the games that were actually played, WeAreDePaul only earned 7 points. If I scored it 6-5-4-3, he would have actually earned 12 points. Ridiculous, IMO. The way I scored it, he got 6 points - which was much closer to his actual confidence levels.
