There was quite a long thread of discussion about this. No one would/could say what circle or ellipse or arc the so-called "radius" was part of, or what made it a radius other than the fact that it was centered on the shadow's edge. 

> The reason that it was changed from a radius is that Brad thought that it should be described, and defined in terms of its appearance, not in terms of the underlying implementation.

I was not the only one to think it should be described in a way that was measurable, testable, and author-predictable, and that the measure should be visually equal (in some way) to the length authored.
