** * [cos(delta * sigma) + GAMMA]

**
** where sigma is the spread factor,

** delta is the difference in radians between the
** angle you are shooting at and the actual
** angle of the klingon,
** ALPHA scales down the significance of sigma,
** BETA scales down the significance of rho,
** OMEGA is the magic number which makes everything
** up to "* hit" between zero and one,
** dist is the distance to the klingon
** hit is the number of units in the bank, and
** zap is the amount of the actual hit.
**
** Everything up through dist squared should maximize
