Default School me in the art of backspacing

I'm trying to get this perfect in my mind before I order a set of wheels.

Tell me if I'm seeing this correctly......Consider this scenario:

You have two wheels. One wheel is a 15x10 with a 4.5" backspacing. The other is a 15x9.5 with a 4" backspacing.

Now if I've been reading the material right, a 10" wheel is actually 11" wide from lip to lip because wheels are generally measured from tire bead to tire bead. (Taken from Team III website.)

So in our cases above, we have in all actuality a 11" wheel and a 10.5" wheel.

Backspacing and front space make up this distance.

So if our 15x10 wheel is actually 11" wide and has a 4.5" backspace, then there is 6.5" of front space....or pretty much wheel dish.

Likewise, if our 15x9.5" wheel is actually 10.5" wide, but has a 4" backspace, then there is again 6.5" of front dish.

So in both cases, we have the same dish, but the 9.5" wheel is gonna be an inch narrower and therefore sit back in the wheel well further.......

Is all this correct reasoning?
