I think you are all missing the point. The answer is that an OEI approach should not even commence unless the candidate is assured of getting visual off the approach. That is that the cloud base is well above the MDA or DH. If not stay at cruise altitude, if possible, and divert to the alternate. I won't go into what I think about teaching OEI missed approaches in light GA aircraft. Different story in Transport category aircraft.
