A worthwhile bit of information but it still dances around the crux of the matter. How much effect did the German air attacks have on British seaport cargo throughput?
It has an effect, but no effect on the British war effort.
As has been said to you repeatedly, the port handling part of the supply equation was not the determining factor in the import/export equation. Because the British had an excess of cargo handling capacity in their ports, the attacks on the London docks were basically worthless. The British had the capacity to move goods all around the british isles using their rail and canal systems. The rail system was not under any significant strain either, though it was old.
You dont seem or want to understand that attacking the strongest link in a supply chain is about the dumbest thing you can do, because it has no effect on that supply chain. This discussion is merely underlining the very poor targtetting choices made by the LW during the battle.
