I think it should really come down to the delegate's report to the WCA, as thankfully the judge for this solve is the delegate, and we can get a true report on the official inspection time on the stopwatch. The current inspection regulations allow for a huge amount of timing error due to when the stopwatch is started and stopped. If Bryan stopped the stopwatch when it said a time that was less than 15 seconds, then video should not be able to overturn this, as that was the official inspection time.
If, however, the stopwatch did read a value that is greater than 15 seconds due to the small girl distracting Bryan, then this is a moot point. But if we really want to have more precise inspection time, then we should either change the regulations or accept that not all competitors will have exactly 15 seconds inspection time. Correct me if I'm wrong, but it used to be that the cover went back on the cube after inspection time for this reason, right?
