If not mathematically then statistically.. (Score 2, Informative)

Statistically it might be possible to describe this properly, if such a relationship did in fact exist. The problem here is that all the variables seem to be ordinal values and they give no instructions on how to convert them into cardinal values in terms of their function. That makes it also quite interesting how they got the constatants. On the other hand would every properly derived formula suggest that the implied relationship does not exist. Then again that seems quite boring.
