If possible I would like to make a very general statement about a film's shoulder (reached due to overexposure). Is it true that in general the following set of curves will represent the relationship in the shoulder area to increasing development times ? Note dev times might get too short to achieve Dmax as I show in the lowest curve.

If my graph is not general enough, then what generalisation could we make about the way a curve's shoulder is affected by increasing dev times ?? (you must ensure sufficient over exposure is given to define all of the shoulder right out to Dmax)
