To quantify the strength of the rock mass, among many mathematical formula, RMR approach uses six parameters RMR=RQD/Jn*jr/Ja*Jw/SRF?

my question is the formula is used to quantify the rock quality but parameters "Jw/SRF" creates a confusion because Jw=water pressure in the joint, this reduces rock strength but formulated as a nominator and SRF=stress reduction factor is formulated as denominator. how it could be? is there any one who clarify this please?
