Fast ships are fuel hogs?

[Kamog]

This fuel usage calculation always seemed weird to me, too. Let's say you have a ship with 6 quantum engines. You travel 9 spaces and use up 540 supplies. If you travel only 6 spaces, you use up 360 supplies.

If you have another ship with 3 quantum engines and travel 6 distance, you use only 180 supplies.

So the fewer engines you have, the more efficient your fuel use. Can't the 6-engine ship simply turn off 3 of its engines and attain the same efficiency as a 3-engine ship?

Anyway, the fewer engines you have, the greater the distance a ship can travel before running out of supplies, even though it is slower...
