I think Iron Man 3 threw the pattern out the window and that was responding to Avengers one foreshadowing one joke (they skipped the foreshadowing in Iron Man 3 and just had the joke). Then there's Captain America with one foreshadowing and no joke. GOTG was going to be no foreshadowing and two jokes, but ended up with just the one scene (like IM3).
I think the point is there's no pattern anymore. The only rule is they'll at least have one scene (except The Incredible Hulk, which obviously had no post-credit scenes).
