I just did the EDDH RNP RWY33 approach in bad weather and it worked perfectly. If everyone is telling you that you're doing something wrong, perhaps it would be more productive for you to study the problem instead of attacking those trying to help?
Here is the setup to the approach, RARUP1 STAR, flew down to platform at 4000 in PROF with no problem. Then brought it down to platform @ 3000 ft with V/S mode, so once the aircraft was in NAV and ALT HLD mode, gear down with flaps in final configuration and slowed down to approach speed, I hit the "FInal 3.0°" in the FMC and then PROF just before the FAF (SOSNAX) where I got the cyan arming indicator and then it followed the profile nicely down to minimums.
