The company's interpretation of the 1000' gate forces your hand. And there are quite a few. Then, once you come to decide which is your preferred option, the wind of the day might necessitate using the other one.

My baseline is F2 160kt to 4,4 then L/G DN, (pause 2 sec) manage SPD. The idea is to have at 4,0: idle thrust, gear down, wheel door closing. When L/G cycle is completed, F3, F4: the trick lies in achieving setting of F4 soon enough, before the A/THR comes to protect the F-speed while F3 are out.

In a real IMC, LG DN at 4,5 and manage SPD at the same time keep a bit of margin to avoid raised eyebrows, but 155 or even 150 by 4,0 is what you get.

Especially wise guidance in Uplinker's second paragraph.
PM's liaison with ATC will spoil the show somewhat.

Short version: the deccelarated LP/LD Gear UP approach method on the SA Airbus is not really compatible with ATC fixed speed 160 to 4.0D
