Holy smokes, I got my wish.
Miles' team ran at the Florida Relays this past weekend.
Their 4x100 won the event in a very impressive 40.42. They also ran 40.39 in prelims. Very impressive time for a high school team. Miles was the anchor, but it appears they put their two fastest short sprinters on the first two legs. Those two guys also came in first and second in the open 100, running 10.16 and 10.42. Those times, especially the 10.16 are blazing for a high schooler.
Their 4x400 placed second, but actually ran faster than the time previously discussed in this thread (3:14.xx). They ran 3:13.74 this time. Miles again was the anchor and split 48.39. Their third leg ran 49.84. Their first two legs averaged 47.755 each, with one of them being the guy that ran the 10.16 100 open. That guy is a burner.
