There are several ways Reserve can get RR pay other than 4+ hours late/X-day interruption.

One is 23.L.4.Note (uncovered legs over 14 hours must go to Open Time).

Another is 23.L.11.c for an illegal turn time. It has to be a legal turn time at the time of reroute. Each station has a proprietary number, but a 10 minute turn ain’t legal anywhere.
