We are also dumb, because of this. If things change slowly, below the error detection threshold, the computer will continue to adapt to the new situation. Road workers get killed, and a great number of the accidents are from the workers that slowly become acclimated to the environment. The MegaSquirt controller uses a historical algorithm for EGO feedback when using it in a closed loop configuration. It has a maximum correction setting that limits how much the feedback can modify the system, and then it will let you determine if the corrections get written to the permanent tables or not. Which is all to say, "It ain't simple."
