Look at it this way: the deflection reading on the Loos gauge due to
stiffness is a constant, totally independent of tension. With no
tension, 100% of the deflection is due to stiffness. As the tension
increases, more and more of the deflection is due to tension, until you
reach a point where the contribution from stiffness is swamped out.
How can it be any other way?
