Actually, there's a "value added" part of the formula, but not what you're remembering or even close to the ratio you're thinking.
The part of the formula you're thinking of applies to bookmarks; not reads.
There's a "bookmarks" sub-formula, the results of which are multiplied by either the total posts or the total posts in some recent timeframe (I don't remember which) then divided by some number I don't remember but which is used so that the bookmarks portion of the formula doesn't make us deal with scores in the millions.
The bookmarks sub-formula assigns a value of 1 to a bookmark, then adds 2 points if the person who placed the bookmark has posted in the past 30 days. That way I can include the relative activity level of the bookmarker as part of the formula.
I think I determined at one point that because of the multiplication and division that's happening, a bookmark placed by someone who actively posts contributes about 5 times as many points to the score as someone who doesn't post. But that number varies because the number of points that bookmark contributes is also determined by the overall posting activity on that board.
Keep in mind, too, that though the score is reported as an integer, the calculations aren't based on integers. It's not a simple matter of 1 bookmark adding one point or even some multiple of 1. I think there are scenarios in which bookmarks (whether "active" or "non-active") contribute fractions of a point. And other scenarios in which a bookmark is worth multiple points.
Short answer: I haven't a clue how it really works anymore, but I know that post reads don't factor into it.
