BRCGS Pack 7 , Section 2.5.2 & 2.5.3

Hello all : )

HARA Plans - When determining hazard significance using the classic 5x5 Likelihood vs severity matrix:

• Should a significance rating be assigned NOT considering PRP control effect, and then PRP listed, followed by a second significance rating where PRP effect IS considered? 
• OR, should there be only one significance rating including PRP control effect because 2.5.2 says " likelihood of occurrence, considering PRP in the absence of additional control"?

it's late in the day here, and my brain is seeing both sides of the argument and confusing wording.

We have only PRP's as control mechanisms (thus far) if it helps.

Thanks !
