I am not sure about any delay, could not find the information in the books.
What is in the book, and many pilots overlook, is that the wind information in progress 2/4 (B777) is in reference to the airplane heading and not track, or runway. This is relevant as you may be crabbing into the wind. So when you de-crab, your crosswind component will increase. Ok, but who will look at that when de-crabbing......impossible in practice....good to know, but in practical terms, irrelevant!
Crosswind (X/WIND)
Displays left (L) or right (R) crosswind component relative to airplane heading.
