Might be smart to extract this into refundFeeRatio or something, since we use it a lot.

Also it might be smart to not set the refund multiplier in tests to 0.5 since then you don't have a way to assert correctness of feesReturned vs feesDeducted since they are both same. Not critical but maybe a todo.
