I am currently in a fairly extensive exploration expedition and get to sell my bio data whenever I get within 1000 ly of a carier. (1000 is the magic number for me)
This time I had for 4 billions worth (incl bonus). I haven't sold any cartographic data yet as I'm saving it for someone who mayne can use it for bgs when I get back
I often play in vr but not always because it is a quick way to get burned out with the game. Although putting video on an overlay somewhere on the dashboard (or usually ny characters feet) helps.
