I'm trying to figure out my strategy now. I passed 2000% multiplier over the weekend, and got down to about 100 donuts. I'm back around 1,000 now.
I want to be in a position to:
A) Store my SH buildings. I think I will soon store them equal to my next increase in multiplier, until they ar all out of my town.
B) Stop KEM farming. Yes, it's the cheapest way, but it's a pain. Rat Trap Trucks or Blood mobiles work well. I'll still KEM farm 25 at a time, but no more.
C) I never considered it a race to get to 2K% and I don't consider it a race to go higher. I refuse to buy Mystery Boxes, I don't want all the stuff they give. I could have gotten to 2K% quicker with them, but i don't care. I can just buy and then hide JEB's. They are out of the vault now, but but I did buy several boardwalk fountains today.
D) I have enough cash on hand to buy plenty more Rat tap trucks, but I don't need the donuts now. I need to build those 3 new aspirationals.
There may come a point when I will get more cash and donuts than I need. I don't want to work hard to get there. I just got my first warning, 7200 items. Translation: I don't want to deal with what other folks already have had confront them trying to design their town.
