Are you just doing something like git log v2.6.16..v2.6.17 | grep ^Author: | sort -u| wc -l
or do you have some script that maps addresses to people ? One person may appear once in 2.6.20, and then a half dozen times in 2.6.21 if they use multiple email addresses for example. (Also, typos, and people using full hostnames in their sign-off's instead of email addresses skew this somewhat).
I'm guessing the latter, due to the graph thing you did. Pointers?
