That's the correct way of doing. That's the way Airbus teaches. Gear is a heavy user, no manufacturer recommends gear+flaps with flight controls requiring hydraulics as well. In Airbus selecting Flaps2 moves slat from 1 to 2 but the flaps a long way from 0 to 2 if gear is also lowered it definitely increases demand on the system. Similarly when gear is going down the doors are open and the drag is high till they close adding to it flap3 doesn't make sense. It will be nice if someone can produce something more than I do it.
