The Financial Management Regulation I led you to is a simplified version of the applicable laws (not regulations). I’ll look at it this evening and dig out the info you need. In the meantime maybe you could visit
@Guardguy11 @Provis @chaplaincharlie and
@RetiredColonel-MikeT all of whom might have experienced the pay situation you described.

Edited to add #1: CRDP is no longer a pay term; it is Concurrent Receipt of military retired pay. A reservist with 20 good years cannot receive their reserve retirement and possibly Concurrent Receipt until they meet the age requirement . A 15 year medical retirement results in zero Concurrent Receipt.
