Update - Release here: http://www.question2answer.org/qa/51517/new-premium-plugin-user-statistics-per-month
I have developed a new plugin in draft that can calculate all points per month. Opposite to the best-user plugin which saves the total points each month, this plugin can (re)calculate the entire history of points.
You see exactly where your points originate from :)
Who would be interested in buying such a plugin?
I still need:
1. translate everything to english
2. provide an option to recalculate all userscores for the history
Currently the statistics are shown per user. So there is no all top users list yet.
