Abstract: Embodiments provide various systems and methods for using operating parameters of a drilling system for improving a drilling performance of the drilling system, including monitoring, determining, predicting, and/or controlling tool face orientation, tool face wagging, returning the spindle to a neutral position, and spindle reaction time. These systems and methods may be used together in combination with one or more of the others, or all together in one combination, or may be used separately, and may be combined with one or more other systems of a drilling rig, such as a bit guidance system, an autoslide system, and/or one or more autodrill systems.
