Ah yes, fair enough. In fact the LRC technique for the 146/RJ isn't even a traditional LRC, it is a single indicated airspeed (235 KIAS for the RJ85) that is used regardless of weight. At heavy weights it is slower than ideal and at light weights it is faster. Something else you can do if range is critical is to disengage the autothrottle and manually set the power.
