Good vectors and hard speed control. First a/c on final 160kts or more until 4 DME subsequent a/c exactly 160 to 4, last one (if there is a gap) 160Kts or less. 180Kts on base, 210Kts with about 25-20nm to go. Don’t lose vortex or it’s coming back to you.
experience helps with the compression after the first a/c passes 4DME (speed control finishes at 4) as there are too many variables wind a/c type etc
