Than again, your experience is different than mine.
That was pretty obvious in W124 section. Where after checking everything else, the owner would disclosure running on inferior coolant.
Bottom line, your chart might have good use on newer cars, where the problem is mechanical or electrical malfunction.
On aged cars, that we usually discuss in the sections I frequent - the most common problem is chemical build up and my first suggestion is get infra-red and read the radiator temperatures.
Meaning what you put as 7th on your priority ladder, would be the first step for me.
Just real-life variations.
