That was my point exactly- annotations that require annotations. Think of it from the reader's perspective: they see $2 million highlighted in an article, they mouseover, click, tap or otherwise interact with it. But then a bubble comes up and gives them a different number that can't possibly be immediately interpreted without further reading and maybe analysis. It's confusing to be presented by conflicting information at a glance. Annotations are meant to take a reader to primary evidence or otherwise supplement an understanding. However, primary evidence isn't always so precisely straight-forward to be able to do that sensibly- that was my point.
