As the others have pointed out: a 10-min TOGA limit could increase RTOW in the case of an extended 2nd segment, i.e. limiting obstacles infringing the company default EOAA leading to an increased EOAAmin.
Exactly what I was referring to, think of mountainous terrain such as the Alps and airports in the foothills surrounded in all directions. Most normal operations do not require 10 minute limitation but sometimes it is required on certain runways at MTOW.
