5/8ths isn't what it's advertised it to be. I'd explain it, but I have
to finish watching SG1 and then F1 practice session 2.

It has to do with "ground planes" and the fact that they are mostly
fictional in this case. And that the second 5/8ths doesn't have the
needed "ground plane".

I'm sure someone else will explain fully.
