Perhaps more relevent is going to be the brake energy required for landing (average Concorde landing speed was around 160 KTS, how does that compare to the 744?).
Not sure that the landing brake energy is more relevant, the RTO case must involve much more energy - a high speed, greater mass and less room to stop.
Anyway, at Max LW of 285 tonnes, the Vref25 is about 159 and Vref30 is 153, add 5 for the increment and you have the threshold speeds. At a more usual landing weight of 245 tonnes, they reduce to 148/142 +5 respectively.
