Interpretation
Lisa (J-DR) started at 8:37 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 13 minutes head start on Lisa because the Runner wave starts 27 minutes after the Invitational wave. On foot, Lisa ran 1:32:59 and Edward ran 48:29 — Edward was 44:30 faster than Lisa. Lisa took official place 834th (time-based 964th) and Edward took official place 2nd (time-based 1st). Edward was faster on foot and finished ahead on the official clock too. Biggest swing: Edward gained 17:33 from Muir Woods to Cardiac.
