Mark may enjoy a discussion along those lines from August 2008: http://www.fer3.com/arc/sort2.aspx?y=200808 It's the thread that begins at the bottom of the page, about "taking four stars". Note the sights in George Huxtable's challenge problem are symmetrical about the mid time. As I said back then, "Further analysis of Huxtable's simulated observations shows that solving for slope vs. using the known slope does make a difference -- if the observations are not symmetrically distributed around the center time." Dear old George. I miss him.
