If you trade efficiency for faster cruise speed, is your trip being shorter a net win for fuel costs?

No, because drag scales with v^2. Going 10% faster requires 21% more power (and thus fuel), but only reduces trip time by 9%.

AIUI, drag scales as v³, the reason doubling horsepower adds only a trivial amount of speed.

You are both right, there are v^2 and v^3 effects, and depending on the speed regime, one or the other will dominate.

In the pilot books in my country the v2 is the most significant factor, v3 is not even mentioned in General Aviation.
