I don't understand what http://korma.wmflabs.org/browser/contributors.html is for (a custom Wikimedia page which says "Contributors of code merged through Gerrit."), compared to / in contrast to either http://korma.wmflabs.org/browser/scr-contributors.html (default page).
Are there different criteria applied explaining these different numbers?:
- Contributors' "People All-time" lists "Chad 12429" followed by "Ori.livneh 4742".
- scr-contributors' "Complete history" of "Code Review Users" lists "Chad Horohoe 47061" followed by "Jon Robson 17343".
If contributors.html it considered useful, then it's broken because the last quarter covered is 2015 Q1. It is 2015 Q4 now.
