Time evolution of W_max, upper limit on the global amount of energy available to heat the ICM, in units of the jet input energy E_jet (Eq. (7)). The vertical dash-dot grey lines represent the beginning and end of each jet event. Most re-orienting jets converge to a value of about 80% towards the end of the simulation; they all release more energy than the 0000 case, which does not exceed ~65%.
