Looks like you might have been right anyway.... during the time period of her missed mat, she would have had to run at 5:32 pace, which is dramatically faster than the 7:xx miles she had been running....
Edit - the weird thing is that the obvious place to screw up on that course - missing the left hand turn to go to the first out and back and instead just continuing straight to the second out and back (which was very well marked with a continuous line of cones spaced like 12 inches apart, she would have had to average 8:53 in that section to make the splits work.... and then speed back up by a ton just after passing the mat. So that's probably not what happened.
