>>> Problem: Programmers with negative productivity cannot be represented on the same log scale.

This is similar to the problem of price-to-earnings ratio. The ratio goes asymptotic as earnings goes through zero. It would be better to quote earnings-to-price ratio. Another screwy reciprocal unit is miles per gallon for cars.

Now that I have an EV with 130 miles of range, I’m finding miles per kwh to be much more useful than efficiency.

I’d bet range anxiety was also a thing for early gasoline powered cars, so the early adopters of those probably preferred mpg over gpm.
