I would really need to look at the same paperwork as you have to make sure I have my head around it properly.

However, might it just be the case that Boeing is referring to the WAT limits ? The WAT limits are permanent line-in-the-sand stuff. The obstacle gradient requirements will be either the Part 121 things or whatever is specific to a particular runway, ie highly variable.
