- 100*(K+R) + 500*(C+S) - 400 for novice through good levels OR
- 346*K + 400*R + 500*(C+S) - 400 for expert and emeritus.

- Enemy vessels only move prior to their attack. In Novice - Good games
- only commanders move. In Expert games, all enemy vessels move if there
- is a commander present. In Emeritus games all enemy vessels move.
-
- *  If Enterprise is not docked, an agressive action is taken if enemy
- forces are 1000 greater than Enterprise.
-
- Agressive action on average cuts the distance between the ship and
- the enemy to 1/4 the original.
-
- *  At lower energy advantage, movement units are proportional to the
- advantage with a 650 advantage being to hold ground, 800 to move forward
- 1, 950 for two, 150 for back 4, etc. Variance of 100.
-
- If docked, is reduced by roughly 1.75*skill, generally forcing a
- retreat, especially at high skill levels.
-
- *  Motion is limited to skill level, except for SC hi-tailing it out.
