no, i don't mean you're not predicting for me personally.  you're predicting for everyone who uses him.  which is cool if he's really only for you.  again, i wasn't trying to argue you out of your position.  you asked why do it, and i was saying why. 

frankly, you might have the same problems if what i'm anticipating happens.  because you seem to be interested in realism, and what i'm talking about is strictly a (huge and glaring, most of the time) realism problem.  you're predicting how you'll use him just as much as anyone else, and if you go outside that range or do something you didn't anticipate, it might be a big problem.  or it might not (hopefully).  and just to clarify, i don't mean outside that range like wanting to morph to a werewolf.  i mean you get inspired by a photo or painting and want to duplicate that pose, and find that everything responds so specifically you get bizarre and completely inaccurate behavior. 

there's a reason NBM is optionally tied to movement instead of only done that way.

and again, i really, really hope i'm wrong.  i'm just trying to let you know that your approach might make as many or more problems as it solves in actual practice, even if they don't show up in testing.  and since it's a problem i run into so frequently, that most people avoid by doing exactly what you said you were trying to avoid- using very specific and limited poses- i thought i'd say something.
