I don't know how to find or provide some information useful for
benchmarking purposes: the only thing I'd consider important (and
measurable) is the total number of female contributors and chapter members.
Females are so important in Italian Wikimedia projects and chapter that
their role can't be measured and I had never thought of measuring or
increasing their /number/ in the board.
Anyway, I've added some stats and trivia I like on
https://meta.wikimedia.org/wiki/WikiWomenCamp/FAQ/Perspectives/Italy , I
hope they're somehow useful.
