Thanks, AtomKraft!
Your words fully match with what I've used.
I'm feeling safe when using mental 'milestones' - 180 up to 10 nm, then 160 up to 4 nm, then decelerate and go in landing conf. Even when not asked by ATC
(but gears down only at 5 nm, then immediately the landing flaps selection; all completed before 1000' AFE)
Just was slightly astonished why E-Jet has the special 'duplicate Flap 4' position, not like Bus. Now it's clear - just the procedures issue, not a bug, just a feature
