Okay, I've been struggling trying to figure out why some B&W shots look so deep and rich and some just look gray. I just wasn't getting why my "pushed" stuff looked better. It was because I was matching the processing to the scene, it was NOT about the EI, it's about the right contrast for the scene. In my head I had coupled contrast control, expansion and contraction, absolutely with pushing and pulling. Yeah I'm slow sometimes, but I do eventually catch on.
