When set to 100% the aim point is adjusted on the assumption that the flare sink rate controller instantly achieves the sink rate set by TECS_LAND_SINK. when set to 0%, no aim point adjustment is made. If the plane consistently touches down short of the aim point reduce the parameter and vice verse.
