The same language about finishing in the required time is in the Dopey instructions, and they never bothered to check times and verify you after every race. They only checked the photo match after the last one and not the time. They say this to keep hundreds or thousands of people from taking advantage of things. It's the same reason they say that you must be in your corral by 5am in order to run, on the bus by 4am, etc. If everyone pushed the system to the limit, they'd have some serious chaos on their hands. Adding language like this gives them an out if someone shows up at 415, misses a bus, and is late to the start. I wouldn't stress over the pacing wording. As long as you finish in front of the balloon ladies and your picture matches the one they take at the expo, you'll be fine.
