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.

Cruise is at 0.78 to 0.79 mach depending on the fuel consumption rate. Mach is the speed of sound and varies by altitude, temperature and air density. At 35,000 feet altitude, mach 1 is 663.5 mph for standard conditions. It is a few mph faster for lower altitudes and a few mph slower for higher altitudes. For standard conditions in the 33,000 to 39,000 typical cruise altitude, 0.78 to 0.79 mach would be 515 to 525 mph.
