Inspired by a few things over the years (don’t worry,  it’s almost certainly not you), I have created a new metric,  called the KW metric.

What this measures is the amount of knowledge imparted (K) relative to the amount of words used (W).  As knowledge (K) is hard to measure, we use a proxy, which is defined as “the theoretical minimum number of words that could have been used to impart the same amount of knowledge”.

A KW close to 1 is optimum; and as you use more and more words to communicate less and less knowledge, your KW metric rapidly approaches 0. I’ve yet to decide if it should be expressed logarithmically – what do you think?
