There's no timing/scoring software that I know of that automates the results scrubbing process. I'm on the results committee of one event where we flag people from the full results pool based on whether they've missed split mats, and we do a full review of all award-winners where we check for missed or suspicious splits and also review their photographs.
Once we do that we contact anyone with a flagged result and give them an opportunity to present photos or other evidence that they completed the full route. This full process, including contacting folks, takes a 3-4 person committee an hour or two a day most days for 2-3 weeks (which can be time that's tough to find while doing other post-race wrap-up).
So what I'm saying is, if you invent that software, let me know. It would make my post-race a lot easier.
