Jeff:

I for one would rather see time scaled down for the higher jump capable ships but not on such a "drastic" level of cost.  Maybe by using all the fuel available for a quicker jump, but it still could break the rules of the game by causing your enemy to out think your jump calculations.

If  the full Jump Number is 150 hours, then there should be the capability for a Jump 1 ship to accomplish an in-system "micro-jump" in less time than the full Jump 1.

Back of the napkin calculations

Jump 6 accomplishing a Jump 1 ==> 150/6 = 25 hours (28 hours at 168 hours)

Jump 6 accomplishing a Jump 5 ==> 150/(6/5) = 125 hours (140 hours)

The question is, how do you go about determining the time for a micro-jump.  Would it be proportional to a parsec's distance since this is considered the distance of a "jump hex?"

Thoughts....
