Kudos on your continued efforts!!!
I think this really means something.
Not only do barnacles, on different planets, spawn different sets of rates, but the barnacles in the super crater on B3-2 planet 2 spawn a different set than the rest of the planet!
I wonder if "outcrops" can also tell us the same story of a planets make up. Meaning every planet would have a unique material composition.
This could mean that not only are we looking for "rocky" or "high metal content" worlds, but "high metal content with concentrations of: niobium X%, yttrium X%, vanadium X%" and so on.
This chart could point us in the direction of a clue we're missing. It is very important. I wish I could find it on the front page, would be handy when I need FSD materials
