[stackalytics] Reported numbers seem inaccurate


In working on the project update for Ironic, I too have noticed wild
inaccuracies.

For one contributor, I found it reported 1 commit for a specific
contributor in one screen, but when looking at the data differently
that same user showed four different commits.

Looking at the commit count reporting for ironic-group, it also only
shows about 200 commits for stein, but when I manually dump the data
out from the `git log` output I count in excess of 600 commits.

It also reported like 63 contributors for stein, but I get 123 based
on just the commit log author/co-authored-by data. I totally get that
there are lots of edge cases to cover in any UI to show insight, but
the data just does not seem like it is accurately reporting.

Is it time for us, as a community, to whip up something that helps
provide basic insight?
