Wiggle-matching can be used in places where there is a plateau on the calibration curve, and hence can provide a much more accurate date than the intercept or probability methods are able to produce. Radiocarbon dates are generally presented with a range of one usually represented by the Greek letter sigma as 1σ on either side of the mean.
