WOW! Another DQ and semi-fake (well really actually fake) name. Another onion layer...
Well, I looked up the official 2010 USATF Rules for road racing. Gun time and your actually finishing place is your official finishing time and place, not chip time. Also see rules about displaying number. See below from rule 243 and 245:
Thus, technically speaking, one cannot be 'kipped' in a race by official USATF rules as you might have altered your race strategy if you knew someone were on your heels.
Rule 243: (Display of number rule)
3. Runner's identification shall consist of running numbers pinned securely on the front of each runner's uniform and displayed throughout the race. The registration list will contain each runner's name and running number.
4. Any competitor who has been found by the Referee and/or Jury of Appeal to have gained an unfair advantage by intentionally shortening the route of the race ("cutting the course") shall be immediately disqualified from the competition. See also Rule 163.6.
FINISH LINE RECORDING AND TIMING
1. Officials at the finish should record each number as the athlete completes the race, along with the athlete’s finish time. The order in which the athletes cross the finish line will be the official finish position.
2. The timers shall start their watches or timing devices at the flash/smoke of the pistol or approved apparatus or at the first moment a competitor crosses the start line, whichever happens first. False starts in road races should not be recalled.
3. The official time shall be the time elapsed between the start of the watches or timing devices resulting from an appropriate start signal and when the athlete reaching the finish line. ******The actual time elapsed between when an athlete reaching the starting line and finish line can be made known to the athlete, but will not be considered as official time.******
