"i dont want judge the system he is how he is but he is the same for all."
I guess this is the point: some will reasonably question the validity of the algorithm with regard to the finer details of CSGO. Yes, it's fair in as much as it's without bias for whichever teams it's collecting limited data from; however, the team-ranking algorithm (and rating 2.0, too) do not make sufficient control for all the variables at play in any give match-up. Rating 2.0, for example, makes no control for the direction of fire at the point of a kill, the lack or abundance of information at play between the teams, it doesn't factor in the luck involved in some running shots, jumping shots, un-scoped awp shots (or any of these simultaneously), and those are just a few examples that come to mind. I don't care to list everything I can think of. Sorry for that. Maybe another time. Nevertheless, the point still stands. An observer well versed in the game mechanics and the finer aspects of strategy and meta-strategy, provided he can mitigate his (or her) biases towards the teams and individuals in question, will always be a better final analysis of any given match, until such controls can be accounted for. The trouble is: most of us are not capable of this.
