A peacetime convoy escort force estimate

Did the Royal Navy estimate how many sloops a convoy would need?

Exercises suggested roughly eight sloops plus three or four destroyers for twenty merchant ships, though wartime needs could differ.

China Station exercises suggested that a convoy of twenty merchant vessels might use three or four destroyers and eight sloops. The neat peacetime result was a planning estimate rather than a guarantee for wartime conditions. The force mix shows destroyers and sloops operating as complementary escorts.
