Ah, finally the ND bundle drop.

I'm going to stick with my theory of sales covering the entire week but the further back we go the less weight sales hold. This would make a far more stable chart.

For example and for arguments sake, let's say an item sells 1000 a day for the week .The last 24 hour would account for 1000. Now let's say every day back, the sales half and half again for a further day back. So the sales assigned to that item would be 1000, 500, 250, 125, 62,31 and 15. That equals about 1980. But it one of those days is real high then it could still carry a big number to hold it number one even though it's being outsold at that very moment.

If the chart did only represent the last hour, it would be chaotic

I'm seeing all of these theories based on that one monthly update. Here we have the WiiU, a console that gets soundly beaten in America every year, at #1 and yet for some odd reason we're trying to extrapolate why the biggest selling console was at number #1 in the hourlies. My first thought would HAVE to be that the monthlies are wrong, even though perhaps the hourlies are wrong. Let's just wait for the weeklies to see how that looks because right now I just find it strange the WiiU is leading in the monthlies.

Finally it's gone from #1. Can't wait for tomorrow's boost!

Was Amazon the only place selling the Wii U for $250? If yes then that explains it being number 1.

Anyway I disagree with you on this GG, it's not the first time something strange like this as happened. The monthlies and hourlies are probably correct, what I suggested explains the occurrences quite well.

You're disagreeing with ME! How dare you, Sir?

I'm just going to wair to see how the weekly updates.

Weekly updates include cyber monday which isn't a part of december, so that won't help you.

But it's part of December NPD.
