Add normalized valueType

[darenwelsh]

If you plot score (based on an algorithm giving more weight to unique-pages edited than sheer volume of edits) versus views, the comparison includes an overlap. For every edit, there is at least one view (I think there might even be two or three "hits" depending on the sequence of loading the page, going to the edit view, and then loading it again after saving). So it might make sense to adjust the score-views-ratio valueType or the score valueType (or because doing both would doubly effect the calculated ratio) by subtracting the number of edits per day from the number of views (within the calculation). It might be more accurate to subtract the views on any page that was edited that day (by that competitor).

Below is an example to help visualize the correlation of these three variables:
