Hocus's followers: increasing fortunes and barter

Can anyone please post examples of fortunes increasing from one of their games? Has anyone seen fortunes go to +3? What about increasing the amount of barter for a high roll? Or adding new things to surplus or want?

In a game I'm running, there's a Hocus who gathered a lot more followers by preaching the hell out of a hardhold, and thus got an increase for barter, and also lost a lot of followers during a grenade fight, and lost the the original barter growth they had.

Oh, and I -almost- gave someone's followers a new source of barter, but they were all like nooooooo, I don't want to cultivate extremely dangerous narcotics, pffffft
