It's a great document and one of the clearest explanations I've ever seen.
I'm not sure it helps this situation though other than establishing a helpful target let-go current.
See the diagram below and note the bit circled. That wouldn't be there in the situation this thread is discussing.
Isn't the point here that in all cases there's an 1000 ohm path straight to earth with at least 230ma current flowing, whether you add a parallel path through a unbonded pole (roughly 1000+ 110 ohms using value to MET) or a parallel path through an bonded pole (roughly 1000 + 66 ohms)?
Am I thinking about this right or losing marbles?!
