Always look at a range of top-cut (capping) techniques: There is no single ‘magic bullet’ technique for top-cutting a set of data; the top-cut chosen will depend upon the nature of the data, the support of the data and the location of the sample points. Best practice is always to look at two or three different approaches to cutting and see if there is a commonality between one or more methods. If the outcome is sensitive to the top-cut level chosen then it will pay to carry out a sensitivity test on different cuts.
