Cutting the number down

A good cover is the whole ballgame. Most of the energy replaces heat lost from the surface, not heat delivered to people.
Holding temperature usually beats cooling down and reheating, because reheating a large mass of water is expensive.
A waterlogged cover has lost its insulation value and quietly doubles the standing loss.
