Type I response pattern as reflected in the piece size-age relationship for poor-medium (a) and good-excellent (b) site qualities. Regime denotations are given in Figure 3. Note that the intersection of the horizontal dotted line denoting the specified operability criterion with a production curve indicates the earliest age at which the piece size operability criterion is attained.
