If you read my earlier post referred to, then you should now understand that the PR algorithm presumed that, as is the case with academic works, citations would be to other works which supplemented and/or complemented the citing work; i.e. that, in general, such citations would be "yes" votes." In that case, a sum total of votes was equal to the no. of "yes" votes.

On today's web, OBLs may be "yes," "no" or "neutral" votes. Here, the sum total is an absolute total only. I.e., in PR, 1 + (-1) = 2, rather than equalling zero.
