Already erased my post. You don't need to keep worrying about it anymore.

Also, by the way you are saying, Brock's heat wave should be instantaneous. 

Since someone who was paying close attention at their moves couldn't get there, it would be also impossible for the characters who are there to react.

Anyways, I liked the post I made, but I'm getting really frustrated with all this discussion, so I'll just be a side character and do nothing at all for more than 20 posts :-)

Oh, and all the teachers are observing the students, taking detailed notes & etc from over 100m. That's totally something a human being could do.
