Wonderful! Thank you.

A bit. But it doesn't make it that much more complicated (fortunately).

Not surprising. I excel at confusing concepts. :-)

Thank you very much! I really appreciate you taking the time to explain
this properly.

Yes. Looking for some good meat.

Fixed.

Fixed.

More than a little bit.

Again, thank you very much.
