Laying in bed all day listening to the radio gives less 'finger distance travelled' but doesn't mean greater productivity. I'm being facetious to point out that 'finger distance travelled' is not a meaningful measurement (at least not to me).
Laying in bed all day gives you zero MPG. It doesn't mean that your bed is the most efficient vehicle in the world, it only means you fail at basic logic.
"Finger distance travelled" is a proper metric. If you have a better one, write an article and see how it does.
