not sure if this is the right thread to ask but i figured you all here are lao jiaos so can probably shed some insight.

let's say there are two officers, A and B, both same rank. but A's years of service is 5 and B's is 4 but both appointed to a supervisory role at the same time, does that mean A's performance/CEP has not been as good as B's? Thats why he took 1 more year?
