Give me a strategy for getting to 500% multiplier and/or donut farming?

@168sean168 now that i am officially a "troll" i am definately going to post an explanation in the near future. multiple linear functions never yield an exponential function. (not entirely true but that is a different story)(and i didn't even consider limitations here (yes that was a joke)) there is an optimum somewhere and it is not maximizing your percentage.
