1. A track-type tractor incorporating a system for preparing and presenting optimum performance, the system comprising:

  • a processor;

    a display coupled to the processor;

    a plurality of sensors configured to provide operating condition data and operating state data to the processor; and

    a memory coupled to the processor, wherein the memory stores computer-executable instructions that cause the processor to;

    process the operating condition data and the operating state data into a current performance value;

    process the operating condition data and the operating state data into a set of performance values over a range of input values, the input values including at least one of drawbar pull, track speed, track slip, blade load, or blade height;

    identify an optimum input value from the range of input values corresponding to an optimum performance value from the set of performance values;

    generate target input values as a subset of the range of input values selected to include the optimum input value;

    unevenly weight the target input values compared to input values outside the target input values;

    display the weighted target input values; and

    display the current performance value relative to the weighted target input values.
