Well, just check the System Maps (and Influence distribution) of Systems where the Outposts/Stations are >250000Ls away.
You'll quickly find almost noone is servicing them - for good reasons.
Place a Community Goal into a Station 100Ls from the Sun and see how many Players are actively contributing into it.
Then do the same with a Station 100000Ls distance from the sun.
Same story.
Just doesn't work.
Unless you enjoy viewing a 20min Supercruise screensaver.
I've learned to
endure it to some extent - but even I go AFK when I'm traveling in Exploration to tag some >250000Ls distant Sun.
And even despite all that - I can only take it for so long.
IMHO :
SuperCruise works just fine for upto ~10000Ls.
Anything beyond that is slowly running into the Screensaver area - simply useless to watch, Playability content = zero, annoyance factor = exponential with number of exposures.
Anyway, tons of good suggestions have been made about that deep during Beta last year already. Frontier knows all they have to know to improve the situation.

Seriously ??!)
