Editing Ship Crew (section)

===Grade modifier===
A ship has a Grade Bonus equal to (square root of Grade Points)-10. This Grade Bonus acts as a modifier to actions such as firing weapons or checking for system failures. A low number of grade points may result in a negative Grade Bonus which will then act as a penalty to such actions. A ship with 100 grade points is considered an 'average' crew as they have no bonus or penalty.

The Grade Bonus is applied in the following situations:
* Accuracy of beam weapon fire. For example, if a ship has a 60% chance to hit and the crew has 400 grade points (and therefore a 10% bonus), the chance to hit is increased to 66%. If the crew has 900 grade points the chance to hit would be 72%. If a crew has no grade points (and therefore a -10% penalty), the chance to hit would be 54%.
* Rate of Missile Fire. When a missile is fired, the reload time before the next missile can be fired is reduced by the grade bonus. For example, if a missile launcher has a 40 second rate pf fire and the crew has 600 grade points (and a 14% bonus), the rate of fire will be reduced to 40 x 0.86 = 34.4 seconds. As Aurora moves in a minimum of 5 second increments, this bonus is ineffective if it reduces the firing rate by less than 5 seconds.
* System failures (related to overhauls). The chance of failure is reduced by the bonus (or increased for a crew grade penalty).
