No Dick. I'm not answering your question because the answer is in the manual for your equipment, that you clearly haven't read.
It is a combination of your equipment and how it interprets the coding of the approach, which then gets wrapped around live data at the time of flying.
Its not a hard coded, fixed point. It is interpolated. And because different nav systems all do it with different logic the result will be slightly different each time.
No one is saying you cant use it, and no one is saying its not safer. The only thing we are trying point out is its advisory, not guidance and that is why the CAAP makes no mention of it.
Your welcome
