DoF = FarLimit - NearLimit

It's a distance between two points (two parallel planes to be more precise).

That's a range, right?

No, certainly not!!!

The difference between 2 and 5 is 3.

It is not the range (2, 5).  That is an entirely different mathematical concept.

The same argument applies whether 2 and 5 are pure numbers or whether they are points at a distance of 2ft and 5ft, respectively, from some origin.
