RNP on 737NG FMC 10.7 and UP

Hi everyone.
Does Any body know the changing logic of the RNP at the 737NG FMC?
It should be 0.5 approach, 1.0 Terminal, 2.0 en route and 12 oceanic. But we observed 5's and 10's en route as well...
Thanks

You have three different RNP values.
1: Default RNP, such as 0.5 (approach), 1.0 (terminal area), 2.0 (en-route)
2: Navigation base RNP: Values may be unique for certain segments.
3: Manually entered RNP.

I do not fly the 737 but shouldn't the RNP for approach be 0.3 nm?

That would be RNP for an RNAV approach..and not the default value of 0.5
