8. Engine is set sloppy rich, into a four cycle mode. Engine is no longer
exhibiting two cycle performance, power and RPM have dropped to
where normal flight maneuvers cannot be performed. Raw unburned fuel
is misting out of exhaust on every other revolution, smoke is excessive.

This is where I draw the line. K&B calls this point "slightly rich".
I disagree with K&B's assessment, or description of rich running.
This is NOT what K&B calls "slightly rich". It is what they call sloppy rich, just like you did. K&B's definition of sloppy rich is very similar, though not as detailed, to your number 8. I've posted it before, no need to repeat it. I will however, repost their definition of slightly rich:
"SLIGHTLY RICH running is a rich type setting, but it is fast enough to pull the airplane. This is the setting you normally look for before launching the airplane because the engine will run leaner when airborne."
I don't know how you set your engines before launching the airplane, but I certainly do not set it according to your number 8, which you said is equivalent to K&B's slightly rich. I set it mine in the 4 or perhaps 5 range on your scale, which most people, including you and K&B, would call slightly rich.
