The "Questions Per Day" calculation for beta sites seems to be broken, at least for the new Travel site. I first noticed this when the private beta launched, but I thought it was due to the partial first day or something. However, a few days later, it's still wrong.
If we look at the Area 51 entry for it, we see 2 days in beta, 7.7 questions per day:
If we then hop over to the beta site, we see we're now up to 108 questions (and I think we were probably at about 80 or so at midnight):
So, it seems that the questions per day calculation is somehow broken for beta sites.
