Yup, that is http://thread.gmane.org/gmane.comp.version-control.git/16223/focus=16267 > [1] This is all theory, and I don't know how well git actually finds > such deltas, but it is probably better to have a dense tree of > deltas rather than long chains.

Yes, your guess is perfectly correct here, and indeed we did an extensive work along that line in 2006/2007. For an example, see http://thread.gmane.org/gmane.comp.version-control.git/51949/focus=52003 The histogram "verify-pack -v" produces was in fact done primarily in order to make it easy to check the distribution of delta depth.
