Microsoft Excel OpenOffice.org Calc
In the name of all that's anal retentive, I've compiled statistics for ALL of the Song Fu competitions. I have it in Excel and OpenOffice.org formats. If you're interested, bookmark this page. I'll keep it updated here.
UPDATE 2010.01.03: I've added a "% of Total Votes" tab. Now you can see how each song did relative to the others within a competition round. This eliminates misinformation that arises when comparing the raw votes of two rounds having different participation. (A song can have the most votes and do poorly, percentage-wise, compared to other rounds.) This makes it possible to do meaningful trend analysis.
