Not quite sure what you mean by the multiplier - does the channel read how many different files are on each game, and feedback literally a per person set of data rather than, as I presumed, a per system set? If that is so, then the Wii Sports data would suggest that far less than 10% of Wii owners are submitting data, and if that's the case, the raw number of players indicated by the data for other games may also be less than 10% of the actual figure (though acknowledging that such a figure is likely to vary depending on how much the game lends itself to a gamer who uses the Wii's online functionality - one would expect, for example, data for VC/WiiWare games to be based on a much bigger percentage sample than that for Wii Sports [i.e. well above 10%).
