It sounds more like you are trying to stir the sh1t to me. You say you want more info so you don't make the same mistake? IF, and its a big IF, this is true, whats to learn as it seems a pretty straight forward mistake, no doubt helped by the end of a long overnight easterly longhaul. Don't let the Autopilot disconnect and not notice, hows that for a lesson.
I think your reasoning for stirring this up is not for your benefit, but as I stated above.
