For example when it is set to its default value of '80' it means that between the checking intervals the CPU needs to be on average more than 80% in use to then decide that the CPU frequency needs to be increased. -sampling_down_factor: this parameter controls the rate that the CPU -makes a decision on when to decrease the frequency.
