I believe that the AFPS15 MAcr will also be on AFPS75 as AFPS75/15 pension earners. The PIA could well be the fact that promotion to MAcr a couple of years previously, and possibly PAS supplements, means that the ‘lurking’ AFPS75 has now picked this amount up. Everyone is different as it depends on time served, rank and pay scales. But I suspect that your Masters getting close are being ‘stung’ by the 75 portion, that accrues at uneven rates, rather than the 15 portion that accrues at 1/47th
You can see the uneven accrual rates for AFPS75 in the Pension Code tables here:
