Our team also has groups of 8 that we rotate throughout the day for scouting. We assign each student a set of robots to look at, and if they have more than one robot in a match, they give the sheet to another person. Before every match and eliminations, our coach and drivers get data about their alliance and the opposing one, which helps a lot when strategizing.
We've been refining our scouting program for a few years, and this year's is in the white-pages if you want to look at it. It may seem like an information overload at first, but is pretty efficient. Here's the link:
