Sounds interesting: Anybody willing to code the SQL query for
implementing the h-index? I admit I have no real clue how to map
the "citations" mentioned on the WikiPedia reference with package
uploads. Uploading a new package version is quite different from
creating a new package - measuring both the same is unfair. My
"highest number of upload per year" was just reached in a QA effort
which did not costed a lot of time - way less than if I would have
created a medium complicated package from scratch.

Yes. I missed to mention this. It is the same idea as it is behind
the mailing list statistics.

Don't undersetimate the Debian Med team! :-)

(but in the end there are probably NMUs - at least Matthias K. and
Moritz M. will not count themselves as part of the team). Also Dirk E.
was basically doing some NMUs for R packages.

Yes. Those people in fact exist as the top20 graph shows.
Unfortunately the graph just becomes quite big if you take more than 10
people into account.

This is a good idea but as I said I need a better algorithm than on
the WikiPedia page to acomplish this.
For completeness I also calculated top20 for Debian Science (with an URL
you can guess. I also have calculated the graph for some other teams
(as you might have seen once you found the *.txt file).
Thanks for your input
