I think you have explained it better than the book as the manual was very vague. I know the distributor is different from the auto.

The only question I have in your explanation is about the tvs switch. I do know that GM used the same switch or one like it on a lot of engines. If it is wax operated it would seem like it would only be good for one time. Once the temperature melted the wax it would permanently be connected to the source.

It is suppose to return to normal when it cools. Dick Paterson told me that he has seen a lot of them that no longer work. I did not ask in which position they failed. I took Dick's recommendation, removed mine years ago, and permanently hooked my distributor to the ported vacuum port on the carb.

Actually my PO in California bypassed the TVS before I got the coach. I just removed it from the intake manifold and put a brass pipe plug in it's place. When I later pulled the manifold to install blocking plates, I painted the entire manifold including the plug. The plug now looks like it was installed by GM.
