To be honest, I think we'd all be better off concentrating on photography than maths. Yes, the difference between 50% and 40% is 20% (actually, it's 22.22% recurring) If you start at 50%. But, we're not starting at 50%, we are starting at 100%. So, if you got 50% of 100% and now you get 40% of 100%, you have lost 10%.
