Consider the following scenario: Suppose that the base 
has
been adjusted by the base 
. Occasionally we will be
concerned with partial adjustments, and to this purpose for the partial
adjustment results we suppose that we adjust initially by the base
, and then partially by base 
; and that 
represents the complete adjustment by the base 
. Suppose
