[Ragnarok-X]

Kevin:

If one core holds 3000 supplies, and my col ships moves at speed 7 with 6 engines taking 30 supplies each:

7 * 6 * 30 = 1260 supplies per turn. - 300 which are generated by one core = 960 supplies per turn. 3000 / 960 = 3 turns.

Means the ship will be depleted within 3 turns.
