Your airplane will exhibit better speed stability flying at LRC rather than MRC.This is the reasoning behind the LRC definition.th Aug 2006, 15:18.

LONG-RANGE CRUISE AND COST INDEX. The relationship between LRC speed and ECON speed is different for each Boeing airplane model. As stated, LRC is based on a 1 percent penalty on fuel mileage, while the ECON speed uses CI as an input that is based on a more detailed accounting of actual costs.However, it is possible to derive a CI for normal cruise conditions that approximates LRC in terms of the cruise speed that results.s stated, LRC is based on a 1 percent penalty on fuel mileage, while the ECON speed uses CI as an input that is based on a more detailed accounting of actual costs.
