Alternative rating.

I suggest a coefficient of 1.5 for tournament matches and 2 for the semi-final and final. The number of points awarded for winning a tournament should be slightly reduced to a reasonable level. If we differentiate between the levels of tournaments (their categories), then two levels seem sufficient to avoid overcomplicating things. For example, if the participant pool cannot be considered truly representative, the coefficient could be reduced to, say, 1.3 or 1.8.
