Regarding your claim over Sigma-15 - I wonder how you explain that system which according to you "just emerged", already has RM base and even RFP docking ring in it (what is something you don´t build overnight). I recommend to read infocards about objects in that system before jumping forward with "this is new, lets claim it".
Personally, I would love if devs would have introduced new systems they way "here are new systems, what would you do?", but they didn´t, they implemented them with already created history. Thus claiming it newly discovered is...weird?
Edit: I guess we should speak with each other because when stuff introduced in ooRP way is handled wrong way inRP, it could end with real mess.
