practical best range application?

possible.

Wouldn't it simply be your airplane's best glide speed? Or am I missing
something?

Of course if you can't avoid fighting a headwind, you'd have to do some
math with ground speed vs. fuel consumption at some higher airspeed to
find max range. Or is that what you're looking for?
