A multi-variant question indeed...
First off..the criteria assumes all engine for the missed. EO procedures are custom. There are NO calculations assumes with any criteria for EO.
Not sure what you reference is, either FAA or ICAO...but neither address EO in design criteria.
EO procedures are emergency only.
Remember, and most forget, these are MINIMUMS. If the chart states an MDA, then you must calc you DA depending on your real time performance.
