Statistics
I did some research and I found a statistic that might interest you. 

User:Statistics 
Edits = 32
Article Space = 1 (~ 3%)
User space = 12
Image space = 10
Wikipedia space = 9
Thought you might be interested. You obviously have some statistical expertise, please put it to good use. (As an aside, it's unfair to compare IPs to users since they can be composites of many people and they obviously wouldn't contribute to the wiki space since they don't have a set name to contribute under) Also, I'd be interested to know how you are getting these numbers. I assume you have a bot of some kind (if not I feel bad that you are manually going through all of those archives). [I'm not a memeber of the cabal no matter what  says )]  Segue
