If your average team needs ~10 people to scout, and there are 60 teams at a regional, what you end up with is 600 people redundantly recording what is mostly the same data.
If, somehow, everyone could agree on a scouting standard before they show up at the regional, you could have a representative from every team do all the scouting, and it could probably be uploaded to a neutral location on the web. Then, any fancy metrics/calculations that a team are doing just have to be set up to pull information from that neutral source.
Thus the need to sit in the bleachers and be together the whole event is alleviated for most teams.

Now, how do you get everyone to agree on a scouting standard? Well, for one the regional committee could hold a meeting 2 weeks before the event where everyone shares what data they need for scouting. It would not take much to hash out, as every year almost everyone's scouting sheets contain the same data.
