Wikistats 1.0 and Wikistats 2.0 will use entirely different data streams and approach.
We want to get a notion asap of how and why results from these two processes differ.
Some differences will be accidental (bugs), maybe in the old process, maybe in the new one. Some differences may reveal definition discrepancies. Some could be the result of different methodology.
Once we explained these differences we will have learned a lot about validation issues.
We will start to compare numbers for Simple Wikipedia, beginnning with https://stats.wikimedia.org/EN/TablesWikipediaSIMPLE.htm#editor_activity_levels
So if Dan can produce a simplified version (maybe just one or two columns), both he and Erik can work on quantifying and explaining the differences.
