static hysteresis

stat·ic hys·ter·e·sis

the difference in the value reached by a dependent variable at a particular constant value of the independent variable, depending on whether the latter value had been approached from above or below; for example, in measuring the pressure volume relations of the lungs, if one completely expires and then inspires to a particular volume and holds it constant, the transpulmonary pressure required to maintain that lung volume is greater than if one had completely inspired and then expired to the same volume and held it constant.

The continual-pull approach eliminates the introduction of static hysteresis, which distorts the reading (see figure 1 for the definition of static hysteresis).
This method of determining letoff introduces static hysteresis and is referred to as "effective letoff" (again, see figure 2).
A winch-type device, used properly, allows a continual uninterrupted pull, which l)revents the introduction of static hysteresis.
We can see that this hysteresis effect depends entirely on the direction of movement of the triple line and thus the overall effect is rather similar to the static hysteresis of rubber adhesion in which apparent adhesion is directly related to the direction of motion of the "crack front.
