1. A surgical instrument, comprising:

  • an end effector, comprising;

    a first jaw; and

    a second jaw, wherein the first jaw and the second jaw cooperate to capture tissue therebetween;

    a firing member movable to cut the captured tissue;

    an actuator actuatable between a plurality of settings, wherein the plurality of settings define a plurality of output values of a characteristic of motion of the firing member; and

    a real-time feedback system, comprising;

    at least one sensor configured to assess at least one parameter of the end effector;

    a zone indicator adjustable between a plurality of positions inside and outside a desired zone; and

    a circuit configured to;

    receive at least one sensor input from the at least one sensor, wherein the at least one sensor input defines at least one measurement of the at least one parameter of the end effector;

    select one of the plurality of positions based upon the at least one measurement of the at least one parameter of the end effector, wherein the selected one of the plurality of positions represents a status of a current output value of the characteristic of motion of the firing member; and

    adjust the zone indicator to the selected one of the plurality of positions.
