This comment made me think hard. The chart didn't seem dishonest to me: the Y axis font size is big enough, and abbreviating it seemed reasonable as a way of making more space to show the shape.

But it's interesting to think about in the context of US education standards continuing to plummet: maybe design choices which would have been valid in, say, the 70s would end up being misleading now.

I know we can't run the tanks dry and need I think 20 percent to be considered empty.... But still - 40 is baffling.

SPR are not supposed to reach 0 , and at the rate it is going down it might reach 0 which will be bad

0 is as arbitrary a number as any other
