One More Hole

A Stopping Rule for Locating a Soil Boundary by Auger Within a Fixed Field Day

A paper from the School of Underlying Conditions treats the number of auger holes bored between two disagreeing holes as a sequential decision, valuing each further hole by the metres of expected error it removes from the drawn soil boundary. A bracket earns about one hole for each doubling of its width whether the boundary is sharp or gradual, and on one field day of eighteen holes across six brackets the rule lowers the summed expected error from 78.7 to 67.1 metres, where an even split would have reached 71.2.
