Forget polynomials of the fifth degree, his method couldn't even find roots
of a cubic which factors. (He gave one as HIS OWN EXAMPLE of his method
at work. I would have thought he'd post a polynomial where his method
worked.)
     Checking the link, I see he's changed a few things. He doesn't explain
why you can't choose s = 1 and s = 2 as well. (Probably just because they 
don't give valid answers, I bet. And he's doing his old "rounding off"
trick again, claiming it gives exact answers.)
