Yep, it’s all listed in the Eve Uni wiki.
Hit Math
A turret’s chance to hit a target is calculated using the equation below. It will produce a result between 0 and 1, representing a probability between 0% and 100%. This value is then compared to a random number between 0 and 1. If the random number is greater than the calculated result, the turret misses.
Note: The entire expression contained within the outermost set of parentheses is an exponent.
Angular is the angular velocity (movement between the attacker and the target expressed as an angle in radians per second).
Tracking is the turret’s tracking value (listed on the info window and means how well the turret can hit a moving target).
Signature is the target signature radius (aka target size, a big target is easier to track).
Distance is the range in meters.
Optimal is the optimal range of the turret.
Falloff is the falloff range of the turret.
