Value of a knot

I am no math weenie, but I read an article once than basically said that
climbing higher always pays off, no matter the distance. In other words,
level cruise was less efficient than a plan where top of climb was the same
as the beginning of the descent.

Maybe that's true, as far as it goes, but I've seen many days when I can make 90
knots at 1,000' AGL and 50 knots at 6,000' AGL. You'd be a fool to climb under those
conditions.
