I understand what you're saying AP - the holes lining up and all that, and yes we all make mistakes in SOPS from time to time, but for 2 guys to get what is arguably the most important check of flight deck prep wrong, is to put it bluntly - ODD... And a c0ck up of high magnitude.
I'm not saying there aren't other factors involved - but when you sign that techlog and loadsheet it's YOU who bears the responsibility to get it right..
