Yes I did but I omitted to take the price. However, I think I made a dumb mistake, I was using distances from the Galaxy map, which seem to be *traveling* LY instead of straight line distance. Route planner tools gave me a distance of 100 LY (or so) between Bast and Heike, and the Galaxy Map says 125 LY, which would explain why I wasn't seeing the price I should have.
Anyway, that's my theory, I've just done Heike-CD 75 661, and got 18K per ton.
The equation I've used to model the distance behaviour used the simple distance between the origin system and the selling location and not the real travelled distance during the trade run. I one of my runs I flew a circle without noticing.
