A process for adjusting perturbation magnitude for accurate difference‐quotient estimation of derivatives is described in the following. The process is intended to be carried out sequentially, alternating with iterations of a parameter‐optimization algorithm. A more complex and computationally‐expensive scheme for occasional auxiliary use is also described.
