Hear, hear!!!

I've looked at the old ATM article a few times thinking I might try that 
test, but each time I get to the part about selecting the pin size for a 
given mirror, I just sigh and proceed with the Foucault and Ronchi tests.

I keep thinking that it shouldn't be all that complicated; further, it 
appears that the test would be less prone to "user method differences". A 
tutorial would be a great benefit.
