Tennis Channel showed a pristine copy of this last night so I've been able to make some changes to all my numbers above. I found the point missing on my DVD, so Borg gets one more service winner. He gets one more FHV winner on a shot that I judged "not up." And I found a couple of service faults by both players that came immediately after commercial breaks, missing on my DVD.
So Borg's service percentage goes down even further, to 47%.
