Done no doubt with the best of wishes..but there is no "one size fits all" "exit metrics solution"..his posts are nevertheless useful directly to some and indirectly, via the stimulation of ideas to others..as I said earlier, the thread has merit..many post panda and post penguin threads here, IMO do not ..
