Looks like good info to me. My only nit to pick is the diagram, It would be good to show a nice radius on the ground conductors instead of a very sharp 90 degree bend, And/Or explain in the text that gentle bends are needed in all conductors. I try to explain it as pretending you are bending the conductor around a 5 gallon pail. That provides a nice gradual radius bend. NO sharp bends in ground conductors!
