I kept it at 100% most of the time, but the lowest was when it got down to 97% when my power went out. I think I left in in there for like 43 days, or something. After everything was sold I made a little over 9 mill not subtracting what was put into the coffers. So, maybe like 6 mill profit. I also got 2 spirit seed trees, which I'll probably never be able to use.
