Bill, as you know that is essentially the logic underlying 0.3G (which is analogous to the first excellent print). Actually Stephen's summary paper on Delta-X does a good job illustrating how when developing to different gradients you still end up with virtually the same speed (as opposed to a fixed density criterion such as ZS).
