KE busting is a type of calculation that calculates the energy of a planet bust from the Kinetic Energy of the planet exploding outwards, which requires a speed to calc. Although the "no KE faster than light" rule would apply here, so FTL planetary fragments makes this type of calc uncalcable, meaning most people would resort to GBE, or just not calc it.
