Title: Rewrote the "handwritten" version to be faster

(~ 200%) than the Accelerate.framework approach
by getting rid of the square root (not needed
for relative comparison of non negative values)
and accumulating the result in the outmost loop
without writing/reading intermediate results to
the arrays.
