That would imply that a taller rider should sit further behind the pedals, and a shorter rider would sit forward of the KOPS position, simply because of torso length, not pedaling effectiveness. One of the basics of bike fit is to move everything else relative to your correct saddle to pedal position, and not try to adjust reach by moving your saddle. The correlation with crank length discrepancy has been discussed in industry and among custom builders for decades. These days, at least shorter cranks are available, which makes this a little less common on smaller frames.
