None of the options shown all those example charts require waivers. They are all provided for in criteria.
Sorry cant agree with that, .52 is very 0.30 specific on approach and RNP 1. there is an option to go to a smaller RNP, but that requires approval from 420...if you are a 3rd party developer.

"The standard MA construction is a continuation of the final approach course. The OEA expands at a 15° splay from the FAS RNP value to a value of 1.0, using a 40:1 OCS slope ratio"

"Dsplay = 7.464(1−RNPFAS )" the standard calculations have some of these values built in such as the RNP approach to RNP 1 missed splay distance.

The 8260.52_V7.4 spreadsheets that the FAA requires us to use has this hard coded as well...for the MA splay, Formula 4-1, the only input is the RNP value for the approach...and the VEB OCS Form 3-17 is hard locked at RNP .3...
