Autoratchet on do more goals was broken for some unspecified-but-probably-embarrassingly-long amount of time, but I did some debugging in there last week or so, and it should now have the same result as if you manually ratcheted to that value. Major caveat: autoratchet doesn’t play nice with future changes / breaks. So if you schedule breaks or changes in rate in the future, you probably don’t want to also have autoratchet on.
Autoratchet on do less goals is actually using an entirely different algorithm, and you can’t ratchet yourself any closer to the edge than blue, I believe.
