gogul: Well, if you agree that the proposed "how fast does one play" statistics can lead to false conclusions, than you must agree with me that "if there would be a 'move speed rating' as a further setting for tounaments" it would lead to the same wrong conclusions as well. People would be banned from tournaments because they recently played a lot of games againt people in just the wrong timezone. Or people might get frustrated that their tournament isn't fast because it has a mixture of of players from different timezone while the statistics weren't based on that. Or someone might change playing styles for whatever reason.
If you want a tournament with fast play, create one and use whatever time parameters you find acceptable. Don't allow or disallow people to enter because of some statistic that doesn't mean anything.
