I don't think you understand statistics, do you? That's the point of giving a standard error on your result: to qualify how well or how poorly you know anything. That way your reader can judge if your results are meaningful. If you're too lazy to calculate that (hint: it's only mildly harder than an average), don't report anything. What they did report means nothing without it, not the other way around.
Given how much time they spent on making fancy graphs that tells us nothing of value (see above), they really don't have an excuse.
