It looked worse than it probably was but not in a x-wind when the turn could so easily be overcooked. I lived in the 18 floor of the apartment block with a view of the checker board and have witnessed many who turned too soon and couldn't get back to the 130deg centre line and gone around.
The CX guys, more familiar with the approach than others, let the A/C go closer to the checker board and, given the wind prevailed from N.E., let it help in the turn and cut down the angle to line-up.
The offset IGS was only used to avoid obstructions and get down to minimum...the rest was the old grunt style of flying by the pants.
