Hello
@MarvelousMarvin ,
A few comments about pay.
The DoD rating from 100% to 70% results in your retired pay dropping from 75% x high three average base pay to 70% x high three average base pay.
Seventy-five percent is the maximum payable irrespective of DoD ratings at 80%, 90%, or 100%.
You have already seen your retired pay reduced dollar for dollar in the amount of VA compensation. With 21.5 years active duty (I infer) and a VA rating of 50% or more, you should be receiving CRDP not to exceed the dollar amount of the longevity portion of retired pay which would be 21.5 x 2.5% x high three average base pay.
The combination of residual retired pay from the VA reduction/waiver and CRDP cannot exceed the longevity amount.
Others will likely address the other aspects of your case.
Good luck,
Ron
