Hello, not sure I understand the question and I'm not an expert on this, but I do remember discussions with similar conclusions, in short:
At full throttle an ESC is close to 100% efficiency. Then, as the throttle decrease the efficiency also decreases, which results into more heat to be dissipated by the ESC (energy which doesn't go to the motor). This is the ESC itself, then what is the context; gearing and motor KV who are playing also an important role. Also motor timing should also primarily match btw ESC and motor.
From memory, ESC are generally performing well if not below 85%. If you plan to reduce the headspeed and you are already around 80%, consider upgrading gear ratio and motor KV, rather just lowering the throttle. Will also allow a better torque to sustain the regime when increasing the pitch.
