In a perfect world, as I said at the start, it is better from the fuel point of view to do one more hold pattern and get a min distance to a 10 mile final at min clean all the way to the GP.
We all know that sometimes airspace/traffic does not permit this. My a/c is 737, but there is not much point in talking 'standard' clean speeds (or is there?).
How close could you get to the ideal (assuming other pilots want the same)?
