Game-style repair and the time available to save a ship

What would five game-style repair charges per Royal Navy ship change in the wartime examples considered?

Many ships suffering progressive damage could survive, but instant destruction and the treatment of torpedo damage remain limits.

The scenario gives Royal Navy ships five uses of a World of Warships repair ability and applies it to Second World War losses. The proposed benefit depends on time: a ship still afloat with progressive damage has an opportunity to use the ability, whereas an immediate magazine explosion may leave none. Ark Royal and Courageous illustrate the first case, while Hood prompts doubt. How fully the game mechanic would repair torpedo damage remains disputed.
