Frank,
You quoted my remark that the Rios' method in Norie is "similar to Bowditch's original method, before that was improved by special tables, and looks to me to be a simplification and improvement of it."
Then you commented: "Isn't that backwards? The method of Mendoza Rios came first. Moore included it in his navigation manual as the "First Method", and Bowditch "inherited" it, to put it politely. He later modified it slightly, but it's fundamentally still Don Jose's."
Now I'm asking you to take a closer look at that method in Moore you attribute to Rios. You'll find it to be a version of Lions, not Rios. Moreover, it has, as I recall, three of those "embarrassing cases." Good method, though. I was using it fairly often, up to a quarter century ago.
