What do you mean by "stronger"? We can't pronounce an edge more than rotating the normal exactly into light direction, for which 0.1 is already overshooting quite a bit (light depth is 0.5). And the bias calculation (which I'm working on a bit currently, btw) is basically limited by the 127 values it can put into the byte into one direction - the shader just has to decide what to do with it.
Just to illustrate, here's the "border" brightness for diffferent values of landscapeNormalDepth and current lightDepth:

(0 = far from the edge, 1 = close to the edge. Note that 0.1 actually has lower brightness at the edge because we are "overshooting" with the normal.)
