Apache,
Not being disrespectful, as I'm sure I've said before, I do admire your ability and knowledge,
But, you need to be a bit above average intelligence to be a cow poker,
Not everyone is in that league,
Even fewer DIYers possess the test equipment you have, iirc you have the baby brother meter from mine,
that's speaks volumes in itself
And, you understand how to use it
Most DIYers have at most a neon (that they probably misunderstand how to use properly), and very unlikely they have any form of half reliable multimeter/continuity tester
Even the best normal DIYer will get it wrong on occasion, the problem is, when, if ever, they realise it's wrong it will probably too late to save a fatality.
