from 2005 but quite relevant to current flagged-revs discussions about loosening restrictions on who can edit what.
This is a very preliminary collection of data and partial results; from a test that does not cover a carefully-selected cross-section of edits or times; with significant periodic variances that have yet to be factored out. It is slightly, but not much, better than hearsay. However, I include the raw data used wherever possible so you can decide for yourself how far to trust the interpretations; and can formulate your own vague-but-true statements based on same. If you'd like to split up a larger data-analysis along these lines, write me about it.
Data scour'd from checks through the last few thousand creations / deletions, as of 09:15 to 09:20, 5 December 2005.
