They want younger versions of themselves.
The system worked for them, therefore the system must be good.
I quote again from The Talking Heads, "Same as it ever was..."
The new and improved two-line PRF is a sop so that it looks like "they are doing something." And for the drones at A1, et al, it was a way to get The Man off their collective back and earn themselves one of those coveted strats.
This is no different than the switch from the old weighted OERs to the new and improved "meets standard" OPR/PRF, and so on back to 1947. And before that back to the founding of our military officer corps. Largely, who you know along with luck/timing rules and always will.
Make informed decisions knowing the rules of the game whether written or not.
