You get good separation between intervals because you can clear the debris out of the drill rods at the end of an interval before starting the next. Within a single interval you don't get any separation; the chips are all mixed together. So you have to set the intervals at the finest level you want to analyse at. If you take 1m samples in the field you can't do 0.5m assays at the lab.
