eroded length jumps to a level of Z = 7 initially and then increases with the number of 

 waves in a manner similar to damage, as one would expect. The initially large value of 

 L computed from a small value of E illustrates that there was quite a lot of stone 

 settlement but not displacement as damage was initiated.
