Someone posted a believeable reason for the late starts. One could start out with the first wave, but leave the dtag behind with a helper. After everyone starts, the helper crosses the line last (not a runner so they wouldn't be noticed, they wouldn't even have to be all the way on the course). The helper meets the runner before the next mat and hand the runner something with the dtag in it (clothes, new shoes, whatever).
Other than that, faking injuries can easily get a runner off the course and back on without drawing a lot of attention. On the back and out type of courses, one could fake an unjust and turn around and walk back toasted the start. Other runners think they injured or whatever, then after passing the injured runner ignore them. Further, folks behind the injured runner just see a guy who was out front and hobbling, valiantly start running again. Maybe even race to the line (not knowing this person has 4 or 5 minutes on them due to the late start)
You spend a lot of time thinking about this don't you?
