Anisotropic surface texture

Here is how it looks with Size Pixels doing the tiling - it uses half as many components but it almost looks too flat. What do you think?

Preset number 5 uses a combination of component tiling and Size Pixels, which think has the best effect.

The way it works now is that each little tile reflects the same piece of sky. If I use Size Pixels it reflects the same piece of sky the same way and if I use component tiling it reflects the same piece of sky in various ways.
Apparently the maximum a flat surface can reflect in FF-land is 25% of the hemisphere above it. I understand how to control which 25% it uses but now I need to figure out how to distribute that chosen 25% across the surface as a whole, not the same bit on each tile, and possibly use non-contiguous areas of the sky for the individual tile reflections – as it would occur in reality.

I worked out the macro reflection changes but the more I think about it the more it seems that the Size Pixels slider should do what I am trying to do automatically – since it is supposed to be a global control. That is, as surfaces change in scale their reflections should change too. What it appears to do is repeat the same identical reflections. The problem with doing it internally is that I only have local control, in other words, it will disable 'Tiling'. In other other words, it seems that anisotropy is fundamentally incompatible with seamless tile generators. That statement is probably too broad but until I learn otherwise, I'm giving up. I will submit it as a brushed stainless steel *panel* generator but non-tiling. Besides, next week is dedicated to modeling so I need to wrap this sucker up today.
