Hi, I wrote a little script [1] to get the quantiles (e.g. top 1%) of commit trailers for the git.git project. Perhaps some of you are interested in the result. The top 1% is comprised of just two lines: Acked-by and Reviewed-by. They alone account for 47% of all the lines. The top 10% is shared between 16 lines, and they gather a whopping 96% of the total line wealth. The top 25% is shared between 33 lines, they have 98% wealth. To belong on this group a line only needs to have more than 3 instances. That means the bottom 75% only has 3 occurrences or less. The median is 1. So 50% (in fact more than that; 100 of 155) only has one occurrence. Just to see this distribution visually, I plotted their frequency compared with a Pareto distribution (80:20); they almost match perfectly: https://i.imgur.com/1wQgSlP.png This should not be surprising to anyone that has studied income distributions; in commit trailer lines--just like in people (and plenty of other things)--the rich get richer. Cheers.
