Just don't blame me 'cause you just lost half a day - I have to re-read
the whole thing twice a year to keep it all stright myself grin.

Thanks, I've actually read those articles once upon a time, at least
the residential parts. I see that Figure 2 of that article actually

path". So this reinforces the idea that this is NEC compliant,
although perhaps not best practice.
