Hi Subsonic,
You have to understand that the number of 320 FOs has increased in the last 6 months, leading to less flying hours for everybody. Some SOs have joined the fleet, as well as new joiners.
Look at the big picture, there will be no excuse of not transfering people to the 330/340 Fleet due to crew shortage on 320.
I say again, the 12 values are scrambled for the sake of privacy.
Happy landing!
