Thats's because the teaching is to maintain the "selected" speed i.e. 160kts to 5dme then go "managed" and select the gear down. It generally takes a mile for the speed to drop to 150 kts so we have maintained 160+/-10kts to 4dme.
Wingswinger, there is no +/-10kts. Speeds should be flown as accurately as possible. Having said that, a good start would be if all the Easy 319s were 160 at 5 and 150 at 4, in my experience very few are.
AFAIK, BA and Easy have broadly similar SOPs (
should be stable at 1000',
must be stable at 500') so why are BA 319s so much better at it than Easy?
