So, two Pythons and a Vulture fly into a High Intensity Conflict Zone. There's a Farragut cruiser there and they decide to wing up and take it on for a local faction. It doesn't go well and a few minutes later they've all limped into the the nearby station to lick their wounds. A representative of the faction comes to visit each of them at their respective landing pad and says to each pilot, "We really appreciate what you tried to do for us today, and we know it was difficult, but we've got the funds to give you a bonus for your efforts, and we've got a bit of a tradition here. You can measure between two targetable subsystems on your ship and for every millimetre between them we'll give you a credit."
When he visits the first Python pilot, the pilot studies his battered ship and says promptly "From the forward large hardpoint to the cargo hatch". The representative nods, measures and says "Very good, that's about sixty-eight metres so we'll call that 68,000 Credits".
The second Python pilot studies his badly damaged ship and says "From the forward large hardpoint to the thrusters". The representative nodds, measures and says "Even better, that's about eighty metres so you get 80,000 Credits".
The Vulture pilot looks at his brutally wrecked ship then says confidently "From one shield booster to the other". The representative blinks uncertainly, considers pointing out that the subsystems are close together, measures anyway... and pauses before turning to the pilot. "Uh, son, you don't seem to have a second shield booster. Where is it?"
The Vulture pilot points out of the station entrance and says "About thirty light seconds that way sir."
