WSEX: Official Monthly Thread: June. (#10 of 10.)

[HavanaBanana]

One of the reasons that the Rake is counted as [Rake taken] / [Players in the hand] is that the players are to dumb to understand that the way you describe is the fairest and creates most action.(As seen in old 2+2 posts, where the players cried when it got suggested)
Another reason is that the site has skin's and it would be unfortunate if the rake got divided in such a way that a site who brings in losing players actually are getting less rake paid to them than a site bringing in tight 2+2 ers.
