Thanks for your attentiveness!

After re-reading the documentation I posted originally, it makes much
more sense and I feel much more stupid *smacks self in head*.  Your
definition of "delegation of the parent" is right on the mark, however
I found myself having to read it a few times to have it `sink in'.

I've rewritten it below in a bit easier to read fashion (I think).

The term "delegation to the parent" means that if a logger has a level
of NOTSET, its chain of ancestor loggers are traversed until an
ancestor with a level other than NOTSET is found or the root is
reached.

If an ancestor is found with a level other than NOTSET, then that
ancestor's level is treated as the effective level of the logger where
the ancestor search began, and is used to determine how a logging
event is handled.

If the root is reached, and it has a level of NOTSET, then all
messages will be processed. Otherwise, the root's level will be used
as the effective level.
