To obtain 300 separation within a 4-way, need to track 212 ft from the center

So, 3 seconds after opening there could be canopies anywhere in an area 724 ft in diameter.

724 ft

The corresponding area for an 8-way is more than 1,000 ft. across

Separation is achieved within the group by breakoff and tracking away from the center. Geometry shows that a track of 212 feet minimum is needed by members of a 4-way to achieve 300ft separation - this when everyone tracks perfectly, with equal spacing.
