OK, I'm here in this system now. Used EDScout to scan this system and every one of the planetary bodies are lowly paid when mapped. I admire your persistence and patience in detail scanning so many of the planetary bodies Marbat (or Marzoom). I only Full Spectrum Scan this entire system that's it. Now off to the next interesting system with apparently four black holes o7
Yeah, gotta pick your targets, I certainly don't map everything but I do FSS everything, I rarely come across systems with everything mapped and have only done it about twice when after scanning the valuable stuff there were only a couple of nearby low value bodies between me and the full mapping bonus.
