The wings are as much to blame for passing the trash as CNATRA... I personally know of a pilot who was recommended for FNAEB after 4 (!) SODs in the FRS, only to be given right back on orders from the commodore.
Also, due to the way that MPTS is applied in advanced squadrons it's easier for marginal studs to squeak through.
