That's the response of someone who presumes that I did not read them.

What if I did read them, and failed to apply them to my case because of 
misunderstanding?

You took the trouble to respond, and from a purely 
technical/informational point of view, there is mixed value for me in it.

However, the tone and included presumptions (regarding my reading, and 
my level of understanding octave) verge on presumptuousness.
