Sir,
As I have mentioned here earlier, Merger of CPI 8088 points as in the case of serving employees /Those who retired w.e.f 1.11.2022, may not be implemented to past retirees right now.
Same point has been kept under 'Residual Issues' for the time being as per Minutes of discussion held on 8.3.24.
Only on future date same may happen.
For your information: If merger is taking place right now same is applicable to all pensioners in uniform with change in CPI series 2016=100,and may not have segregation as 5th to 11th BPS as existing.
So all pensioners and employees may have uniform DR there after on implementation of the same,
Example:Present average CPI.9122(138.76)
Merged CPI (12th BPS).8O88(123.93)
New DR -2016=100 -138.76-123.03=15.73%
Just for an under standing .
