Fibonacci error

The "Fibonacci spiral", as constructed from quarter arcs, has about 0,75% error compared to an accurate construction of a golden logarithmic spiral -which has a {[5^(0,5)]-1}:2 scale factor in a quarter turn-. Also note, that about 7,5° turn in every 90° is off the golden ratio rectangle, which the Fibonacci spiral uses as a base.
