I agree with Emma Roys. Guys are completely confusing the two key words, "should vs shall". "Shall" is a must comply. "Should" is, well, a should... Do it if you can but its not the same as a must.
Joe Bloggs... I think this is maybe what you are confusing. I stand by my statement 100%. I've read the OM-A, I know the stabilization criteria. I ask again, please enlighten me where you think it is I was incorrect.
