I don't think it's a problem for the statistics per se. The reports are
only a tool to analyze complex phenomenons and translate them into
manageable items. In fact, we keep adding more stats as we go because
every chart and table leaves us with more questions.

I'm currently thinking that it would be informative to plot the
distribution of the efficiency metrics, instead of simply come up with a
filter to ignore long standing changes with slow/null activity over some
arbitrary amount of time. I think it would be more interesting to see
how many 'inactive' vs 'active' there are at a given time.

In any case, since Sean said that nova (and other projects) already
remove unmergeable changesets regularly, I think the data are already
"clean enough" to give us food for thoughts.

Why owners seem to be getting slower and slower to provide new patches,
despite the fact that the number of patches per changeset is fairly
stable? I'll look into the data more carefully with Daniel Izquierdo as
I think there are huge outliers skewing the data (the diff between
median and average is huge).
