I think I would actually characterize it as a mutual change - obviously the model doesn't change as far as I can tell, but changing the harness and context changes its behavior so wildly that it might as well. Bit of a pas de deux - I learn, I change the context to teach it, it teaches me in turn, rinse and repeat.
