What about Uni Din?

I finally broke down and purchased a Smart Tractor. The owner of that company created another cartridge alignment he calls Uni Din. He makes a very reasonable argument for favoring the inside third of records particularly those cut down close to the label. This is at the expense of the outer grooves. But the outer grooves are traveling three times faster thus a given tracking error has 1/3rd the significance in terms of distortion. 
Has anyone here tried this alignment? If so how did you like it? I will certainly give it a spin as reorienting the cartridge in a Schroder arm is as easy as it gets.

Why doesn't anyone ever mention that the whole idea of alignment by protractor is flawed since it assumes that the Zenith of the diamond is precisely 90.0°?   Zenith being skewed by 0.3° is enough to make alignment A behave as alignment B.  If your diamond Zenith is off by 1.5° it is possible that you will completely miss both null points entirely.

@mijostyn,  Having looked at lots of stylus profiles under a microscope at various magnifications I think it would be exceedingly hard to confirm zenith angle to say 10 minutes.  I'll side with Raul that even with the best tools setting the same cartridge up three times is likely to end up with three different alignments.  At the scales we are talking about here the possibility for measurement error is large and even seemingly small errors can be consequential.
