1. A method of drilling a wellbore using a drill string, one or more controllers, and one or more sensors, the one or more controllers including a drilling controller adapted to control movement of the drill string, which method comprises:
connecting a first stand to the drill string during a first connection;
drilling the wellbore using the drilling controller to control movement of the drill string;
measuring, by the one or more sensors, a parameter;
determining, by at least one of the one or more controllers:
an efficiency parameter based on the measured parameter;
a difference between the determined efficiency parameter and a target efficiency parameter;
instructions to reduce the difference between the determined efficiency parameter and the target efficiency parameter, at least a first portion of which instructions are implementable by the drilling controller;
connecting a second stand to the drill string during a second connection that is subsequent to the first connection;
touching a bottom of the wellbore with the drill string after the second connection; and
implementing, by the drilling controller, the at least a first portion of the instructions to reduce the difference between the determined efficiency parameter and the target efficiency parameter.
