The relation implies that the amplitude in water-pressure forcing does not influence the maximum depth of slip.
Figure~\ref{fig:skin_depth} shows the skin depth for water under a range of permeabilities and forcing frequencies.
The stick-slip experiments (Fig.~\ref{fig:stick_slip} to~\ref{fig:stick_slip_depth_normalized}) correspond to a skin depth of 2.2 meter.
-Practically all of the shear strain through a perturbation cycle occurs within the upper half to the skin depth ($\sim$1 m in Fig.~\ref{fig:stick_slip_depth}).
+Practically all of the shear strain through a perturbation cycle occurs above the skin depth (magenta line in Fig.~\ref{fig:stick_slip_depth}).
