It would be interesting to see more data such as traffic(Alexa/quantcast?), number of employees/founders and so on. This sounds rather silly, but if you collect enough data, you may be able to approximate something of a "formula" for startup success, or at least increasing your chance of success by a few percent. I know PG always says it's the people and not the idea that matter, but looking at your spreadsheet, and assuming PG only picks equally smart people to fund, some ideas/verticals are clearly more likely to succeed than others. I know there's obviously no statistically significant data to back this up, but my hunch is that, given the talents and abilities of founders chosen for YC are roughly equal, it may be the niche or market you choose to enter that can make or break your startup. At the very least, a comprehensive list like this should give YC applicants a rough idea of what types of companies are likely to get accepted.
