At this point, timing does appear to be one of the big issues. I probably should have given DS a watch and "x minutes left" warnings but it was kind of chaotic with other things happening at the time.

DS does need to use his time wisely but he really doesn't have practice with that. Running out of time is an alien concept for him. He had half the time left on SCAT and about a third of the time left on the Explore and really never runs out of time on anything.
