Maybe you don't hear break% directly in the same way you don't 
hear inharmonicity directly. Both are calculated from a 
relationship among tension, wire diameter, string length, and 
tensile strength. While you may not hear the break% or 
inharmonicity numbers directly, you hear the result of the 
proportion mix of the values that produce the numbers.
