I might be overthinking this and would appreciate clarification.

Assuming a 2 day RES GS which begins on an XX day and ends on a RES day. If day 1 is 2 hours of block and 2 hours of DH, will the trip pay 2 or 4 hours above guarantee? I believe DH is considered credit and credit pays on the last day of the trip, but I've got this random thought in my brain that keeps telling me that under this specific circumstance you get paid your block and DH instead of just block. Thanks for your time.
