I can't stress the example enough that we had with the x_THRESHOLD_TOO_LOW=3 -thingy. PSNR went up quite considerable, and the image was all blurred. It was lousy. (Also, a change in the SSIM on the second after-comma digit is within the precision of measurement.)
But suite yourself and believe in the magic numbers ;-)
