Tremulous Ranking generated from logs

[coffee]

Hi!
There is a script to parse a file "game.log" to print a ranking of players called tremrank.py
http://code.google.com/p/tremapi/source/browse/trunk/tremrank.py

It uses the source code from the article The Google PageRank Algorithm in 126 Lines of Python to calculate the scores
 http://kraeutler.net/vincent/essays/google%20page%20rank%20in%20python

You can get two examples of the rankings at this url:
http://tremulous-spain.com/foro/index.php?topic=924.0
The first one is the ranking of 1 year from the server 'TremSpain' (>300MB log files). The second one only from 5-1-08 to 5-31-08

Please, test the rankings with your logs and write your impressions. ¿Is this ranking generator accurate? ¿why?
Thanks!
