Good morning Jim,

Thanks for posting this great link. I posted same one back in 2014 iirc.
Your post brings up a few general thoughts besides your interesting link.

If you think your info or link is good, maybe ask a mod to make it a sticky in the appropriate sub forum.
Housekeeping of posted links. I'm guilty of not doing this. Links go dead for various reasons. Go back occasionally and make sure yours are still valid.
