You should read my post on the "theory of minimum passing score"

Essentially all that matters still is how the top 1% of people do and what the CFA deems to be the MPS, that's it. If the new format helps people(which I don't think it does that much) that will just help others have a better chance of passing, not failing.

Assume the top 1% score 95%, they are likely not guessing on much of anything, so they should stay consistent. 70% of 95 is 67%. That is the MPS, if the new format somehow makes it so that those who would have gotten 66% now get 67%, then they pass.

The other factor is the MPS set by the CFA, I don't know how they combine these two if they are different but maybe they determine based on this test that the MPS should be 68% and not 67%. In either scenario, the level at which you would pass or fail is determined by the top scorers or the CFA institute which should not be affected by the slight increase in chance guessing.

Just my opinion but seems logical to me.
