As a scientist, I find it fascinating that you take a single point value for 2006 and feel you can plot it and compare it with computed statistical values that make up the curves. Do you know what the raw data, and it’s distribution look like?
If you average 1 and 100 you get 50.5 if you draw a line at 50.5, either of the only 2 values look outrageous.
Don’t go where you are so obviously unequipped to venture. It takes a few years to become a real scientist!
