View source for Comparative rankings for WRC

'''Comparative rankings''' remains an inexact science for evaluating mahjong populations, given the tools we have, and the changes in representative samples.

==Ranking expressed as power points (PP)==
As there is no official rankings by country available, the table below is presenting the best, average, median and worst scores, as well as a composite score (the average of all four). Players placing equally with another player are ranked as a half-rank lower, in order to maintain statistical comparability.
