Would you please describe the tests, their methodology, and give 
their results?

Can you tell us how the Rayleigh Criterion applies to binocular 
vision?  (I can see how it would apply to monocular vision.)

PS to silent but concerned parties:  Don't whisper in my ear 
off-list.  If we're going to have people denigrating (dare I 
say sniping at?) the conventional view of SL3D on-list, then 
let's answer the consequent questions here, on-list.  Is that
too much to ask?  The off-list, whispering, conspiratorial, 
I-could-tell-you-but-then-I'd-have-to-kill-you approach to 
answering tough questions smacks of flim flam.  Bill makes an 
honorable effort to answer here on-list.  Please take note and 
follow the inventor's lead.  Thank you.
