Those of us who beat the EPA by 50% or more are guaranteed to be driving below the PSL.
...+1,000 on that!

...it's basically a constant-power curve situation, ie: the product of two numbers, MPH and MPG:

CONSTANT = MPH * MPG

...you "trade" one for the other, against the basically 'constant' product of their two values...hence, the slower you go, the better the MPG (up to the point of lugging the engine); and, conversely, the faster you go, the worse the MPG.

...it's a nice smooth curve, from vertically assymptoic MPG down to horizontally assymptoic MPH. Look at those Corvette FE curves that were posted here awhile back!
