No, it's not. We're discussing wheel poke to ensure wheelarch clearance, and the necessary dimensions are total wheel width (not the J dimension) and the wheel offset.
The back face dimension is required to ascertain whether there's sufficient clearance from the inner rim to suspension components and bodyshell when on lock. Knowing the wheel width and ET dimension it's easy to calculate the backface dimension.

Which is the point made above by WCA, Smash and Mr T, and is why Richard has commissioned special lower offset spline adapters. But even so, you're going to need extended arches or a narrow rear hub conversion of you want to fit wheels with a large offset.
