Do you believe in such a statement?

About BO's new 127mm F/8 achromatic refractor quality:

"I called BO on Monday 12:00 noon EST. Tammy answered and took a
message for Bill about my situation. Bill called me back 2 minutes
later and gave me a brief education on how the BO 1278 is made. I
enjoyed my call tremendously! Bill told me about my objective as he
had inspected and tested it himself. He told me that these objectives
are polished to 1/20th wave after the 3rd polish. That's how fine the
grit is that is used. Also that a good number of these objectives are
testing null, as well as approaching null! That explains the Star
test results with my Ronchi EP. Anyway in Bill's usual engaging
conversation he told me he had one other call that day about what
were thought to be scratches on the objectives. I can't say what the
out come of that call was. But mine I can and will."


1/20 wave? Yes? Did I understood you correctly?

Anybody else believe in such a statement?
