This is a picture of my graph from Rayburn. Your's looking at a picture of a ball of bait on 3d sonar. This is what a ball of bait looks like when it's not threatened. Notice how the long skirt of forage lingers out to the right? They aren't worried about predators.  I'll post another screenshot of a place where I caught fish every cast. You'll notice a difference in how tight the wad of bait is together.
