I'm not sure what you meant about a "one in three chance," but it sounds like you're misunderstanding how we read applications. We don't split them up. Also, there are 4 YC founders, not 3.
The way it usually works is that Robert, Trevor and I (separately) read and rank the applications. Then Jessica looks at the top-ranked ones to see if there are any red flags we've overlooked.
