It's a nice idea, and one I've spent some time watching over, my latest theory being that the directions to the 4 new systems may line with the troughs around the larger circle, but even if they did line up, there is nothing to suggest how far you would have to travel in that direction. Unless the number of obelisks in a group can be scaled into a number of light years that match our distances - haven't gotten that far yet.
Well, we already know the systems, so we could at least narrow it down to a system to search. Anything that might shorten the list for those using eyeball mk. I to search would appreciate that I'm sure.
As an Xbox cmdr I've given up on that method as we have to be far too close for things to generate to realistically be of use there. Sigh.
