If you post a source, I am going to read it and see if it is valid.  

Yours wasn't.  

40% or 85%; neither is 20%.

If you have a valid source for the 20 percent figure, post it. Otherwise, your figures deserve to be ignored, especially when you post data which doesn't match your words.    I pointed that out last time you posted this "information"; you insist on re-posting bogus figures.
