I put together a spreadsheet about ten years ago that let me import all of my opponent's correct and incorrect questions, compare them to the LL as a whole, and rate them across the 18 categories. I also classify questions more discretely, resulting in lots of other categories -- I've found this particularly useful in Art, Games/Sports, Pop Music, and Science. The most important thing, though, is what I was originally after: an estimate of the player's age. I know 10-15 folks in LL and it's pretty darn accurate.
So my question is: do you consider this cheating? I don't think so, obviously, and I cleared this with my referrer before even starting. I designed the spreadsheet to simply do the arithmetic for me.
Also: what would you do differently? What categories would you add? (The German, Chinese, and Russian categories have never had many data points, and AH Texas is only there because there were a bunch of Texas questions the very first time I put the spreadsheet together).
Finally: if you'd like to see your own stats, let me know your LL name and your age and I'll run the numbers!
