Seems to me this discussion drifted into one of annotation, and while that's fine, imho I think it would be more beneficial if another thead discussed annotation issues like displayed accuracy separately.
This thread was about drawing accuracy, and as such, imho, drawing accuracy should not be a function of presentation or annotation. In my experience as little or as much as that may be, data, be it models, or databases, tend to be used many different ways, and as such, it is best to maintain "it" in the most accurate manner possible - you an always dumb it down later.
