Performance pay, like the notorious CS bonus system is so open to arbitrary variation if not cronyism.
The CS system involved a 1 and 2 RO write up and sign off by a 3rd, at one point that was a 2* then when we went purple a mere Colonel.
We were 'pooled' with a number of others in totally different roles and locations. The least bad year 10% got an enhanced bonus, 80% a standard bonus, and 10% no bonus. It was unfunded across the board by reducing basic pay by 10%.
In other words, just rearranging the deck chairs. I guess in Service there will be some low hanging fruit for low award, first tourists, first new role, first on promotion, those that PVR.
There will be a potential for a pay drop year on year.
I expect this will continue until morale improves
