It's said that angle of attack disagree was 22°5 (at least on Lion Air). But the AoA vane does not directly measure angle of attack, but angle of airflow around the fuselage, which is higher - about twice the angle of attack - due to aerodynamics around a long body

That means the error at the Angle of Airflow vane was not 22°5 but about 45°, which correspond to the angle between AoA screws.
