A few seconds? Filling up 450 tons hold of Lakon Type 9 at the steady pace of 1 chunk / 10s (which is completely unsustainable but anyway) and, say, a 1t of mineral / 2 chunks yield => 2.5 hours.Well that's one person's interpretation of "scaling" and "linear" but it's complete garbage, to me.
Slow or not, you're talking just a few seconds as opposed to the several minutes wasted just getting to the station, not to mention docking and getting back out to the asteroid field and not to mention searching for an asteroid that will give you want you want anyway.
Today's mining equipment goes from this

to this

Current gameplay - as fine as it is - surely is closer to picture #1 than picture #2. I'm not sure what is the point in arguing so fiercely against suggestions / desires to see mining gameplay eventually expanded to offer more options and more efficient tools to the players willing to invest big money and take some risks.
