In dithering techniques, you count the error produced, because it is not the same to count a 8 bl : 1wh as black than to count 5 bl : 4 wh as black. In the first case the error is 1/9 while in the second it is 4/9. These errors are propagated forward to the "uncounted" pixels. This way the global error is forced to be 0 (except for the last pixels processed). Otherwise, the global error should have a standard deviation proportional to sqrt(boardsize^2) = boardsize.
