I understand that if, for example, aircraft was 1 degree aircraft nose up at 30 ft, the target becomes 1 degrees aircraft nose down, requiring side stick back pressure to re-establish 1 deg ANU plus required extra ANU for flare.
From day one on A320 (my first fbw) attitude control during flare seemed natural and similar to other swept wing jet airliners. I think Airbus did a great job with flight control laws during the flare.
