Yes, I know this version from Rodger Rosenbaum, since I was part of the 2007 discussion.
Actually, I tried to contact Rodger a few weeks ago, through his private email on the forum, to inform him of my work and ask if he would like to share the changes he made at the time, but didn't get any reply. He seems to visit the forum rarely now.
Does somebody have some news from Rodger, or know how to contact him?
