The turret line in Portal 2 must have been managed using LIFO (Last-In, First-Out) inventory storage method, because if they had been using FIFO (First-In, First-Out), then the good turrets that had passed through before the template was changed would have been taken out first, and GLaDOS still would've had access to them for quite awhile before using them up to the point where they started becoming faulty turrets.
