Thanks, Grandpa Kim.
I am convinced of a few things:
(1) Nothing we have talked about will be as precise as is measured in a chess game/tourney.
(2) Luck will even itself out over a number of games but it is more apparent that it will equal out over 1 x 1 games more as, was pointed out, than multi-player games as they Last for so long.
(3) No one would like being rated in a game of multiple players that would result in a possible loss of 100+ points even though there is a possible gain of 100+ points.
(4) Generally, I think people believe a multi-player game should result in more points lost or gained than a single game but not as much as equal to a single game times the number of players in a multi-player game. (I hope that makes sense)
(5) We want a way to compute scores as people are eliminated from a multi-player game.
