Cooking loss is not the noodle losing starch. It is the noodle failing to hold it.
The cloudy water is a symptom, and treating it as the problem is why so many trials move the number a little and change nothing else. What decides how much leaches out is whether the matrix around the starch is continuous, and that is set in mixing, sheeting and drying long before the water boils. Published work on one gluten free noodle shows the same flour losing twice as much to the water depending only on how it was dried.
