I think you get the best return with 7.5M in the coffers. Correct me if I'm wrong. 10% of what's in the coffers per day, UP TO 75k if you've done both quests. So you'll want to have a buffer of at least 525k+a default 675k, though I have one of about 750k+675k because I check every ten days and bring the nice round number of 750k along with me. Yes, this is right. Except I think 75k is just 1% of 7.5M, so it's 1% of what's in the coffers per day? Thanks for the info, Lielac. It's 10% of what you have in there per day, except that it maxes at 75k per day. So, if you have anywhere between 750k and 7.5M in the coffers, it will take 75k per day.
