Great analogy Terry.
I've always tried to wrap my head around their adjustments too.
The fact is if God is infallible how can anything coming from him need correction? If he cannot lie all things under his direction cannot be wrong by default.
SO
Either God is imperfect
OR
There is no flawless God
OR
He is not directing the WTBT$ because they have been outright wrong; if they were under an absolute fail-safe ruler, this simply couldn't happen. Even if the mortal subjects were presumptuous, their GOD cannot change or lie, so directing a lie would be impossible.
