I've got a point system that I'm working from, but It's ultimately up to @meno (the sponsor) and the other judges if they wish to adopt it as a contest-wide standard for keeping track of where the leading top-5 entrants stand each week and how the top-5 are progressing from week to week.
I've also suggested some special measures beginning in week-5 so as to keep hope alive for new entrants who haven't had the chance to participate in the first half of the contest and/or for those who have but are not ranking within the standing top-5.
Again, these are just some suggestions that I've put forth, and we'll just have to see how the rest of the judging panel, host, and sponsor feel about it.
I'm certain once a system is agreed upon, that @meno or @luzcypher will drop a post to explain it. Thanks for asking though - it's a good question @limabeing...
