Not sure what you mean by 4% of 0.04. That would by 0.0004. 4% (4/100) is equivalent to 0.04. Raw numbers, normalized to a %, expressing the % out of total or % of the change, not sure how any change in perspective that may be associated with putting it one way or another means much. That's all just value association based around a number. Ratio of sources to sinks, that's the only thing that matters with respect to the dynamics of the system. At least for me.
I threw 3% out there.What is your source for "only 3%"? How was that determined?
Evil Goalie said 4%.
There are some estimates of up to 10% on the high end.
30%?...nope.
