The estimate holds your measured evaporation rate constant. Pan shape, heat, lid position and thickening change it, so check the actual volume rather than relying on the clock. The concentration multiplier assumes dissolved ingredients stay in the pan; it does not predict flavour or saltiness. This is kitchen arithmetic, not food-safety guidance.
