212man,
This issue was covered some time ago when Sikorsky and ECF were first coming up with solutions and data to the PC2e performance requirements.
It was interesting that Sikorsky and ECF ended up with totally different interpretations. My recollection was that "we", JimL included, tried to persuade ECF that their position was perhaps incorrect.
If I were to say more it would be based on supposition, a failing memory and a very poor knowledge of the technical basis for the requirements! If more is required I could go and look at my old notes?
Maybe JimL can offer more guidance, technical input and history?
BTW, who is the "proverbial horse"
