Interpretation
David (X-DR) started at 8:49 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 25 minutes head start on David because the Runner wave starts 27 minutes after the Invitational wave. On foot, David ran 1:20:58 and Edward ran 48:29 — Edward was 32:29 faster than David. David took official place 833rd (time-based 675th) 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 13:12 from Muir Woods to Cardiac.
