Motivational statements are almost certainly being read before progession to PA, obviously not everyone is being progressed as the PAs are probably more onerous to review.
Some people are hearing back about the PA the day after their final checking test (someone I know sat the test literally 36 hours ago and already has a PA invite!) whilst others are waiting days having sat it a week ago so it appears to be random when this takes place but it'll be complete probably by the end of the coming week.
