I finished machines 8-11 a few days ago - cleared all machines except for two junk items in machine 8, and had almost 1,000 stones left over.
I had reset machines 1-7 early in week 1 so could have potentially gotten a few more higher level items in machines 5-7, but I didn't want to be under pressure.
Gave me time to get Southern Cross plus blooms from the reissued event in about 4 days.
Now just building my stamina towards max for the one-two hour downtime before the new event is loaded
