show user translation statistics

In the launchpad translation system it currently is very hard to really find which user did what and how much.

For example to know what the most effective translators are (i.e. which translator contributed most to the current set of active strings) you need to parse hundreds of pages.

For JOSM I found, that graphical statistics are a very good motivation to people to complete translations (and with over 6900 strings for a single application it is a large project). I would like to introduce something like "our best" prominently showing each contributor and how much he did.

Required for this would either be a few number of pages where I can get this information (i.e. which people contributed how many strings and how much of these strings are in current translation). In this case I could update my own project page after reading the Launchpad information. Or better would be if Launchpad already would offer such statistics pages. They should be individual for languages and also global for project. And the should be graphical nice (i.e. with colored bars or the like). Display of these pages should encourage people to do more contributions.

Motivation should be either to get better than others of the same language or also to get better than other languages. With the large number of strings I always see people loosing motivation relatively fast after they started, when they see, that after hours of work they only added a few percent. Climbing from place 100 to place 50 in the contributors list on the other hand may be additional motivation.
