A surgical system comprising: an end effector (200; 914; 1404) comprising at least one energy delivery component (230a, 230b) configured to transmit electrosurgical energy to tissue at a surgical site; and a control circuit communicatively coupled to the energy delivery component (230a, 230b) and programmed to: for a first application period, cause the energy delivery component to transmit the electrosurgical energy at a first power level, the first application period starting at a time zero whereby the tissue exhibits an initial level of impedance (Zinit) and comprising a point in time where impedance of the tissue reaches a minimum value (Zmin); for a second application period after the first application period and as the impedance of the tissue rises from the minimum impedance value (Zmin) but before the impedance of the tissue reaches an impedance threshold level (Ztrans) of an impedance transition point, wherein the impedance transition point is either the point at which the level of impedance rises above twice the value of the minimum value (Zmin) or the point at which the initial level of impedance (Zinit) is reached again, cause the energy delivery component to transmit the electrosurgical energy at a power level that decreases at a steady rate from the first power level until a second power level is reached, the second power level lower than the first power level and the second application period comprising a point in time where the impedance of the tissue rises above the minimum impedance value (Zmin);
