The UWR Shriiwook has now been to every sector in the game. I've got the locations of every port there is, and I've seen all there is to see. Also found a fair number of Paladin's old worlds, which is nice.
I've actually found that ENERGY ports are more likely to be next to each-other than any other port. The longest STRINGS I've found, though, are a string of 6 organics ports and a string of SEVEN ore ports. The longest string of empty sectors is only 10.
