A method performed by a harvesting machine control system comprises obtaining bias data indicative of a performance bias of a first harvesting machine relative to at least one other harvesting machine, receiving a settings input indicative of a request to set performance of the first harvesting machine to correspond to performance of the at least one other harvesting machine, based on the bias data and machine settings associated with the performance of the at least one other harvesting machine, determining adjusted machine settings for the first harvesting machine, and outputting a control instruction to the first harvesting machine based on the adjusted machine settings.
