Dear Mud,
I did explain why you were "off topic" as you put it, you clearly didn't understand what the OP was talking about.
Judging by your last question you still don't. In fact, it makes no sense. Your question is equivalent to asking a shoe salesman "if I can't tie my laces is that a size 8 or a size 9?".
And if you can't clear the hills unless all engines are running, you are not only operating illegally, you would also be dead should an engine fail on take off.
What you should have said was "If the requirement to clear the hills is what limits my TOW, is the OCLW then the RTOW?". To which the answer would be yes.
Constructive enough for you?
