How effective this is depends on ship/doctrinal stats. It is the most efficient in responding to the escort needs of convoys and in anti-submarine warfare. Cuz that 1% speed loss is statistically equivalent to a 1. I usually leave the icons in the sea zones so I can see where my naval losses are accumulating.
