It certainly seems extreme, and even very high counts don't seem to affect it
much - I have got it right that low error bounds are meant to be more accurate?

My non-programming guess was that the higher accuracy means that the generalised
averaging takes place in smaller areas, hence the greater discrepancy. But what
do I know?
