In the Dual ENG failure: your goal is the PFD, ND, EWD in that order, and not SD - OVHD. There needs to be a cut somewhere so that you can restart scanning from the top item again.
Why not a technical note somewhere in FCTM? The manuals need to be kept simple so the readers will see the trees and not get lost in the background noise. Remeber the days of 9-item Golden Rules? Turns out they were too much to handle.
