Harder mathematics comparison

Each model answered 27 problems three times. The trained adapter and a control trained with mismatched answers each passed 2 of 81 replies; the earlier prediction adapter passed 3. The study did not show a gain over the control. Difficulty and answer requirements both changed from the earlier study, so the cause of the difference remains unclear.
