Ah! So sorry I missed this. It's been so long since I wrote the game I'm not sure, but I think it must've been 7 as the dice mechanic was originally PbtA inspired.
Okay, so I've been consumed by getting my newest game up to snuff. But I finally got a look into the PDF of CO and the success threshold is indeed in there! It's on the CEO's page, the 2nd, under The Chaos Meter heading. It is, indeed, 7.
