That would certainly be a very useful function -- it wouldn't solve my problem for me but would make it easier to identify core authors. After all, 'number of commits' doesn't necessarily correspond to meaningful contribution -- many of them could be editorial -- but number of lines (or the ratio of lines to commits) could be a much better indicator.

I don't see any solution that doesn't see me browsing diffs -- there's no metric that will solve the problem -- but if your stats work could help me get an output of the form 'here are all the diffs on file X by contributor Y in order of size, largest first' then I think it would help a LOT.

Is there a website where I can read more about your stats/metrics work?
 Beyond the applications to the present problem I have some other
reasons to be very interested in what can be done with git history stats.

Thanks & best wishes,
