I’ve heard same by reputable sources and not just aspirants. If the outline is completely deviant , the examiner won’t bother reading further. If it’s relevant that’s a green or even if it’s confusing , he gives a chance and reads the introduction. If the introduction is a fail then that’s the end. If it’s good, he’ll continue with conclusion and skims through paragraphs to decide what score to award. But again we never know about individual differences. Ofcourse not all examiners follow similar standard. That’s where luck comes in play.
