I think about it as follows:
THR: The signal level at which AGC action begins. Lower number = lower
signal level where AGC begins.
SLP: Wayne is an EE and I'll bet he views SLP as the degree of gain
compression in the AGC system. Thus, higher SLP values mean a higher
amount of "compression" [and more flat] curve after threshold.
I'm a math dude, not an EE, and I view "slope" as the first derivative
of the AGC gain function ... which is unfortunately exactly backwards to
the way it really works. I get around this by assuming "SLP" is a
really weird acronym for COMPRESSION and not for SLOPE.
Maybe that will help you.

I don't know about others, but I tend to forget the
direction of parameters such as AGC "slope". Do I want to increase or
decrease the number to achieve my intended result?
