I know, my question "...performance information is based on the loss of an Engine..." was intended as rhetorical

Good enough, I just needed you to clarify the intent of your earlier statement.

• Published missed approach does not have a climb gradient greater than 2.5%
• There are no positional constraints. I.e. must reach altitude X by position Y.
The EOSID must be used whenever:
• Any one of the above criteria is not met.
• Whenever the commander has doubt about the aircraft's climb performance.
Exactly!
Remember what I said earlier (Sorry, I don't have a set of manuals close-by to quote from, so I shot from the hip on this).
...
All of that said (Please read this carefully), it would seem - following a go-around - that if flying below 1500 feet AGL(All initial climb segments not completed, thus not into the enroute climb phase), AND,
a positive EO "Required" climb gradient is not achievable (see quote above!!!), AND/OR,
if below the MSA, MOCA or MORA (as applicable), AND/OR,
the EO "Required" climb gradient can not be achieved (again, see quote above!!!), AND,
the "EOSID" can gaurantee terrain separation, AND,
FOLLOWING THE ENGINE FAILURE you are able to fly that "EOSID" procedure, from the place where the engine failed , then the answer to this question would appear obvious.
Unless I've overlooked something, I haven't found anyone in this forum disputing this. However, I have heard some pilots on the line comment that it is not an acceptable procedure.
Cheers.
