Yeah, the 50k at that point in the game is meaningless.
There is also the problem that "hyperspace topography" essentially incentivizes you to start the game, take a Dram and then just mindlessly fly in slipstreams to get the abilities unlocked. Since if I dont purposefully farm it like that, then I end up having all gates active and most of the sector explored before I get the slingshot skill. (even though I scan every magnetic field and gas giant I come across). A counter to this would be to scale the amount of points you get for the slipstream travel by fleet size and sensor strength. (Currently the sensor strength buffing hullmod is pretty much useless)
