How come the historical statistics vary over time? Last month I looked at the statistics for Swedish Wikipedia and it had 132 new Wikipedians in December 2012 and 142 for November. When the January stats came now it says it was 139 in December and 144 in November. How is that possible?
Two screendumps can be found on these links:
And while I am asking, is this table available in .csv or .ods so we can play around with it easily?
