They were never to be used in combination with standard coaches, or hauled in revenue service as coaches. This was violated on almost every railroad that ever owned them, including the LIRR. I have seen pictures of a single P54 hauled by a single Budd Car. Second, a fleet of twenty wouldn't have been very useful during rush hour, where trains of 12 cars were the rule on the Port Jeff line and elsewhere. With tons of spare cash to invest in them, RDC's would have been the ideal bi-directional coach during mid-day service, but Diesels hauling standard steel coaches in rotation had to make more sense. Ziel and Foster state that the Long Island almost bought surplus Budd Cars from the B&M, as their passenger service dwindled. New Haven used them well along the myriad branch lines across Connecticut. They just weren't practical for heavy suburban service.
The B&M had 79 RDCs, later supplemented by a number of cabless single-engine RDC-9s. They operated their entire Boston commuter service with them, except for, I think, one round trip covered by their ACF Talgo train (with FM Speed Merchants at each end) after it was bumped from long distance service. One winter, the Talgo did, to quote the railroad, "At terrific job," actually clearing the iron of snow for the lighter RDCs.
The New Haven also operated their whole Boston commuter service with RDCs. This is what freed up the 30 or so "American Flyer" cars from the B&M for purchase by the LIRR.
Now, the LIRR with twenty RDCs would probably have not have had enough to cover the off-peak weekday service in diesel territory. If you figure off peak service on the OB branch would have required six of them (three pairs in alternating round trips), that leaves fourteen for the PJ and RO lines. Weekends, might have been a bit different. An engineering study might have had to be done, to find the optimal and most efficient use of the RDCs, where best to use them, which runs would benefit most from them. Of course twenty of them would not have been nearly enough for rush hour service, but they would have had full employement, I should think, during peak and off-peak hours if they were used intelligently. Perhaps more than twenty would have been optimal. But I also think the LIRR must have figured, they have their locomotives, and they should use them rather than letting them sit around eating up lease/purchase payments.
Incidentally, I think the LIRR also abused the two RDCs and additionally voided their warranty by running the two cars on three engines instead of four to save fuel.
