You think defining tractability as “% of problem solved / extra $” is confusing because the original 80k article defined it as “% of problem solved / % increase in resources”?
It adds confusion in that the term means two different things now and the original definition is more common. It subtracts confusion in that “% of problem solved / extra $” is more intuitive.

I think in everyday usage, people don’t use “tractability” in such a precise way, so the slight change in definition doesn’t add confusion.
