If you develop differently depending on subject contrast (as in traditional Zone System), then you could take Ralph's benchmark and use it as an aim point for Expansion and Contraction. For example N+1 you would want to develop until Zone VII test target hits 1.29, or for N-1 you would develop until Zone IX hits 1.29.
