Well, people who interview when there's a full moon tend to get in, but of course it all depends on what pg had for breakfast that particular day.
Joking aside, it's probably best not to publish that kind of thing so that people inadvertently worry about something they can't control. The only reason to do those sorts of stats might be for pg & co. to check and make sure they don't have some sort of biases, but it doesn't seem likely.
The first part regd. time of the day was asked since PG mentioned (not sure if it was an essay or a comment on HN) that he used to get mundane stuff done during the day, and then code from 9 pm to 3 am.
This is not to say, PG ignores the early interviews and kicks it into high gear for the evening ones; just that if you look at the results, are there any insights or patterns.
I agree that YC should not publish these stats, but if they did learn anything interesting that could be shared with everyone, it would make a good read.
