My rudimentary (but successful) testing was just to start at the calculated length, and take a shot. Note the stars in the corners, and whether the elongation was outwards or inwards. Adjust the spacing in one direction, in my case increasing it, to see if the elongation got better or worse. Keep doing that until round stars. If you notice the elongation direction reverse, start moving in. All done by eye. Keep meaning to go back and measure more precisely, but I'm happy with the results as they are. YMMV.
