How do you account for this once they play their 8th game? Do those smaller swings get recalculated? Where did 7 games come from as opposed to any other number of games? There is one player at the very high end of the GR list right now that has soloed 8 games, for example, but if you look at his game history none of those 8 games really show what caliber of player he is, so obviously it isn't a magic number.
Does the caliber of those first seven games matter? I can see some Playdippers coming over or something of that sort and playing a number of high quality games, perhaps for a World Cup or something similar. Should those games still not be given the same weight?
