A lot of stuff hinges on the 100D rule, and it's a big part of the
arguments over pirate economics.
So my pondering is this: what are the effects of increasing the Jump
Drive limit? Obviously decreasing it makes trade even quicker, makes
worlds much more paranoid about incoming fleets, and reduces piracy.
It's also boring, so we can discard it.
But 500 diameters(x5)? 1000 (x10)? What are the effects of those?
A quick list of what I can think of -
-more insystem development
-more space for pirates to lurk
-if jump masking (can't hit the drive if another jump shadow is in the
way) is used, ships take longer to jump out based on current system
astrography and destination

I would offer up a table of recalculated limits, but I would have to
break out GURPS Space to do it right - and that's quite a bit of dice.
Maybe in a few days, when work calms down.
