The long chain lengths very quickly tail off. Over 60% of the objects have a chain length of 20 or less. If anyone wants the full list let me know. I also have included a few other interesting points, the git default depth of 50, my initial guess of 100 and every 10% in the cumulative distribution from 60-100%. This shows the git default of 50 really isn't that bad, and after about 100 it really starts to get sparse.
