Which project statistics and for what purpose?

- If you mean overall project stats, what would be the point?
We know that the number of AC@H badges must be low; there was only 33years for the entire project! I have returned more than twice the number of results than that whole project managed. It's not a recent project so most people would not be interested. Those that did manage to chip in might be more interested in the geographical distribution. Though I would suggest this would only be useful for strategistic management of present projects (a bandwidth, task size, system requirements map might for example allow for a rethink on task sizes in order to include more WCG crunchers in specific geographical locations).

Team badge counts might be an idea, but I think there are enough stats for overall contribution.

Take C4CW for example, the Overall Run Time is 7708 years, so what you would really be asking for is a detail of badge distrobution.
