Hi Bob. Thanks for your email.
Hoping to move right along to further insights (as opposed to bickering over old ones) - one of the most useful things in my experience, is to regularly call up the local electricity supplier and complain of noise on the line and ask if they could come out and clean and tighten the connections (again). And they send a man-in-van out to clean and tighten the connections feeding my house. It is very noticeable the morning after it has been done - and I am not at all confused about which night they do it.
