There are a few functions that I know VG Chartz hasn't implemented (yet, anyway), and I figured that I could provide some of those on my own site by compiling the data provided here each week to analyze 2008 as it progresses. What I have so far can be found here:

If the higher-ups at VG Chartz would prefer I not do this, then I'll gladly take it down. I just figured it'd be nice to have another way of looking at VG Chartz data as it comes in. If they're alright with it, then I'm open to suggestions on other calculations to make. Though try to keep it to stuff that's not available or easily accessible at VG Chartz. Enjoy!
