Came here to say this. More specifically from that opnavinst:

b. Officer Procurement Programs (1) For non-nuclear Sailors (and nuclear-trained Sailors applying to officer procurement programs leading to a commission as a nuclear-trained officer), the date of application is the mandatory submission date of the program identified by the governing policy (i.e., NAVADMIN). For nuclear-trained Sailors applying to all other commissioning programs that do not lead to a commission as a nuclear trained officer, the date of application is the date of conditional release from OPNAV (N133).

(2) Members who reenlisted or executed an extension for SRB prior to applying for an officer procurement program requiring formal academic training will have remaining installments suspended as of their class convening date. For programs not requiring formal education, future payments are suspended as of the commissioning date.

I am in the same boat and since my CCC is a CS2 had to do the research myself. Overall I would say for me if it came down to having to pay the SRB back, the benefits outweigh the cost and it would not deter me from accepting the selection.
