It is no less accurate...what you are talking about is a sampling
artifact. The actual inaccuracy is the same, the errors in the small
normal method are just less spatially organized. The banding is usually
easier to eliminate than noise...the situation is very similar to the
tradeoffs between method 1 and method 2 or 3 media.
