This is brilliant and immediately reminded me of "wisdom of the crowd" https://www.youtube.com/watch?v=iOucwX7Z1HU (start at 2:00 if TLDW).

Basically average crowd > individuals. 160 people guess # of jelly beans in a jar. Few are close, but averaging all the guesses leads to 4 away from actual.

Would be fascinating if applied to this as well...
