If I can get some data, I would like to do the analysis on pin pointing parameters that helps you get in YC and what are surely a NO-NO. And my hypothesis is that 80% of decisions are based on objective parameters.
This will be most interesting if it's not about "what to do or not to do", which is what most of the online content about the process emphasizes, and is more about "this is when you should/shoudln't apply in the first place".
