I think those numbers are only based on 2 days or so though. I don't know how many days the numbers for Bayo 1 are though. Both of them are for the opening week but Bayo 2 released more than halfway through the week so out of the 7 days being looked at the game was only out 2 days or so. At least that's what I saw when looking at them.
Edit: The game came out on the 20th so it's only been out for 4 days. Not 7.
