Just got my first success, and have been dutifully starting my spreadsheet. Absolutely love picking up Sola, immediately firing her, and still keeping her vote. Makes me laugh every time I think about it. I was wondering if anyone had successfully gotten Chapadoc or Radomil on your council (or has confirmation that they'll refuse). They're the only two I have not been able to get a firm 'no' or their stats from.

You still get to keep her vote? That's so funny - I'll have to try that on a future playthrough!
I was able to get Radomil onto my council (either through Rhetoric or Menace). My notes say "galactic relations 60" for him, but fail to note if that is the only position he can be recruited into or if it was the only position I tried him in.
I got the impression of a firm no from Chapadoc, but I definitely could be proven wrong.
I have most combinations of people and positions I think. A few outstanding gaps, and a really big question mark over what it takes to get Khdarr into a Law position.

Chapadoc has always given me a firm no, at least.
It’s possible to get Radomil. I called out his surfer facade by saying I was a liar too. He has the best Galactic Relations (60) out of anyone I’ve found so far, though the tests to coerce him seem too hard for an early pick up. He’s really not happy about it, and likely spends his time lining the mood wheel with assassins if you do force him to stay close.
