I still prefer "had had had had" though: "All the faith that he had had had had no effect in the outcome of his life"
It's also nonsensical in content: "things from a place, which have things done by the same things from a place, themselves do things to the same things from a place" - it's tautological.
The "had had" example is much more relevant to someone learning English. Often when I construct a sentence with "had had", I question whether it looks right and if I can rephrase it.
You probably wouldn't use four had's in that particular example though - "All the faith that he had, had had no effect..." or "All the faith that he had had, had no effect...".
