I agree with flyburg.
RNAV is not RNP.
The header used to say RNAV (RNP) not RNAV(GPS or GNSS)
RNAV (GPS) is not the same as RNAV(RNP)
This is a very confusing an un-necessary designation for RNP. IF you have the cert for RNP, it should not be RNAV(GPS) which has a limit of RNP1.0.
RNAV RNP should be left for RNP 0.3 -0.1 with the associated equippage and training.
Its the whole crap with enroute and people not wanting to equip/train to RNP-AR.
