I would like to know the type of system you are making these determinations with. Also, can you provide the criteria you used to determine "50 percent"?

Also, can you define "open fluid bridge" as I have not heard of this term. Bridges, such as a Wheatstone, are employed for measurement of resistance.

WHile I tend to agree that cables make a difference, and can understand your general premise, I do not understand your arguements. Having spent 2+ decades in the High Tech field as an engineer and self professed audiophile, this subject can be a vary questionable sector of audio.
