I think that's over thinking it.
What has always worked good for me... Put a bottle of Chevron Techron fuel system cleaner in a full tank of fuel. Drive that tank till near empty flooring it a few times.
Refill with premium, change the oil. Take the throttle body off and wipe any carbon built up off with carb cleaner. Done.
I'd rather not flood an engine all at once with a cleaner. I can't imagine how that is good for things. Going in through the fuel system over a tank full of fuel seems to work just fine. And...best way to clean a throttle body... is take it off and clean it. Quite easy to remove.
