The diagram was from 8260.52 in an attempt to show how the missed surface is determined, and to lead one to the criteria. The criteria is based on all engine for approach procedures. The design criteria allows for turns at 400' for which there is no design criteria to determine the turn capabilities when EO.
There is nothing in the criteria to support EO design parameters, which is why EO are custom designs.
In AUS, I am very familiar with the YMML, YBBN, and YPAD. Some of the Airbus variants have 60' to 67'/nm climb gradients at EO at the high temperatures with the posted MLW.
