"Power Ratings In The New Millenium (and Beyond)
These new terms are soundly (no pun intended) based on the science of marketing, and PMPO is mathematically expressed as
PMPO = Actual_Power * k
where Actual_Power is calculated by the formula below, and k is a constant whose value is approximately equal to one's grandmother's age, divided by the square root of the distance from the office to the advertisement writer's normal place of abode - measured in millimetres, inches, furlongs, statute miles or pounds per square inch - as appropriate, to provide the number you first thought of.
In the unlikely event that the value of k cannot be calculated from the above formulae to provide a totally meaningless (but plausible-looking) final result, a value of between 20 and 50 shall be used."
