Different types of wall splats

I need to know exactly the different types of wall splats and how many their are. I am working on my combo list and I am about to start listing/looking for/soliciting wall combos.

I know that the opponent can 1)hit the wall and bounce off (facing), or 2)hit the wall and bounce of (facing away). I know that sometimes they 3)hit the wall and stick, and sometimes they 4) hit the wall and slump to a seated position.

I am not however confident that these are the only type of wall splat. It feels like I am missing something. I need to know exactly so that I can plan the combo list accordingly. If I am indeed missing something would someone be so kind as to fill in the blanks or if I've got them all will someone relieve me of my paranoia.
