"We can see there are players scoring much better results in tournaments then their PR should say. Ok, the number of matches are small but even Mochy says this during the comment of the Gibraltar final, so this feeling I think is strongh enough in many players."
From my discussions with the top players, who have been top 16 Giants, there are very who do not agree that PR is the best practical measure of performance. When players say they played to win rather than for PR as an explanation for poor or average PRs, interrogation of the matches virtually always show that the blunders are related to obvious bad plays or oversights, and not through some strategic/tactical adjustment.

"In tournaments you must play when you are tired as well, when you record your 100-300 experience maybe you are at your best."
BMAB rated tournaments or applications take this into account. There is no scope for cherry picking opponents and matches are played at real tournaments or specialist BMAB tournaments.
"In a BMAB tournament I would try to play games where the decision are simple (avoiding for example the risk of missed doubles) and to think every time about what XG decision would be."
You can do this but, in practice, if you deviate away from the normal best plays to steer towards some simple games, your PR score will normally suffer considerably.
What is your practical, fully worked out, alternative to PR as a measure for performance? At BMAB we have considered and tested alternative VR techniques to measure winning performance, but unfortunately found this approach unreliable. It isn't difficult to find some small theoretical failings of the PR approach but that is and would be the case for any performance measurement system. In practice, PR works. Consider all the players that have reached Grandmaster level. It is abundantly clear that all these players deserve their status. There are other notable players who haven't yet engaged with the PR process of course.
