Apspirin players on US server and you play on Euro server. Both chooses the server according to there pings.

"It is certainly probable that if you are not lagging, you have an unfair advantage over laggers. "

So if I have good PC and internet, I have unfair advantage?? I don't think it's called advantage. It's more like spending the money for better services.

I don't think ping should be considered because if player A is lagging then it's player A fault and not others. Imagine someone with downloading torrent and ping of 800.. then whole avg ping would be messed up. Either fix your ISP, PC, etc. or don't play game. Why to blame it on others?

Where it will stop if we start considering ping? Then next one would say consider PC specs too. So we penalize player having good PC?

I don't know whole maths of rating but one thing I noticed is:
Neon, you got -ve rating when you had lesser PPM against the player who had less rating then you. Example:

http://et.trackbase.net/index.php?mo...o&idx=21231059
http://et.trackbase.net/index.php?mo...o&idx=21244449

In Aspirin case, his PPM is always higher then the players he plays against with.
Ex: http://et.trackbase.net/index.php?mo...o&idx=21320570
