Ok, in consultation with my co-conspiritor on this project (pix) I've decided to allow ballots to be up to 100 films but the point system heavily emphasizes the top 30. Hopefully this is a happy medium. No one should feel the need to submit more films than they strongly support.
Anyway, the point system will look something like this: 15 points for ranking 1-5, 10 for 6-10, 8 for 11-15, 7 for 16-20, 6 for 21-25, 5 for 26-30, 2 for 31-50, and 1 for 51-100).
Martin, I do want to apologize to you since you switched his list around a bit based on the discussion for any extra hassle involved in that, but in these early days of the process I'm trying to mold the system to best account for the various concerns so it is a bit fluid.
