Models are constantly being upgraded/improved for overall accuracy, which results in less accumulated error out in time. There have been major improvements in the 4-7 day range vs say 10 or 20 years ago. So in many cases the error isn't "off" as much as it used to be, which means less adjustment as we get closer to game time. That said, different patterns can be more or less likely to shift (the super-gurus here track the known biases of the models and can tell us generally whether the scenario is one that is likely to adjust one way or another).
