So thanks to Nerzhull_AI I've managed to tweak settings the way I want them to be (sector is less "saturated" with stars which now tend to be organized in longer clusters/contellations a bit away from The Core)
Here are my settings:
Spoiler
{
"plugins":{
"newGameSectorProcGen":"data.scripts.SectorProcGenMod",
"newGameCreationEntryPoint":"data.scripts.world.SectorGenMod",
},
"sectorWidth":164000,
"sectorHeight":164000,
"AdjustedSectorConstellationCount":250,
"AdjustedSectorConstellationSize":850,
"AdjustedSectorConstellationCellSize":6,
"sectorConstellationRemnantMin":50,
"sectorConstellationRemnantMax":70,
"sectorConstellationRemnantSkipProb":0.15,
"sectorRemnantPresenceLow":1,
"sectorRemnantPresenceMed":1,
"sectorConstellationRuinsMin":80,
"sectorConstellationRuinsMax":100,
"sectorDerelictMotherships": 8,
"sectorDerelictCryosleepers":80,
"sectorCoronalTaps":10,
"AdjustedSectorRndArcs":20,
"AdjustedSectorHS":true,
"accessibilityDistFromCOM":150,
"accessibilitySameFactionBonus":1.0,
"SanguinaryAnarchisticDefectors_sectorConstellationMin_AS":15,
"SanguinaryAnarchisticDefectors_sectorConstellationMax_AS":30,
"BladeBreakerThemed_ConstellationMin_AS":13,
"BladeBreakerThemed_ConstellationMax_AS":25,
"BladeBreakerThemed_ConstellationSkipProb_AS":0.25,
}
It's for sure less demanding than preset delivered with the mod but it works for me 
I hope you don't mind, I've borrowed this preset to use as my own. I like it quite abit.
Also, glad to see the return of
Nerzhull_AI and thanks for his detailed explanation of how things work!
