A Railgun system moves each particle of its trace off its place on the spiral by a random offset on each of the three axes. Each axis gets its own offset, anywhere from minus half to plus half of this figure, in leptons. 30 moves a particle up to fifteen leptons along each axis. Only the Railgun behavior reads it.

The offset is added to the spiral position that SpiralRadius sets and uses the same units. A figure more than twice SpiralRadius can therefore scatter a particle farther from its place than the coil’s radius.

SpiralRadius=6
PositionPerturbationCoefficient=20 ; scatter of up to ten leptons, wider than the coil

The figure changes only where each particle starts. A particle then travels outward from the coil’s center line at its particle type’s Velocity. MovementPerturbationCoefficient varies its direction at random, and VelocityPerturbationCoefficient varies its speed.
