The average Jedi Master can beat the average Sith Lord

Con, the average Sith Lord would not be as powerful as Anakin Skywalker, Darth Sideous, or the other Sith you mentioned. Those are not average Sith, also I would rather you not reference Anakin only because He is a "Dark Jedi" not a Sith Lord. There is a very fine difference between the two which I am sure you are aware of. I think an average Sith Lord would be more among Darth Maul, The Sith Inquisitor/Inquisitors, etc. Also, when you reference how many Sith Lords have killed it really is not fair. Jedi do not usually kill, that is not what their order stands for. They usually try to bring their enemies in or cripple them. How many average Sith Lords do you think would be slayed by Yoda, The Exile, Luke Skywalker, Obi-Wan, Mace Windu, Galen Marek, etc? If any of those characters chose to kill then you would see something catastrophic. Yoda and Luke alone have Force Abilities through the roof...its been said that Luke Skywalker's force abilities were like that of a god once He became a Master. I know these are not average Jedi Masters, however you did the same thing with Sith Lords when you compared how many would kill Jedi Masters and so on. So, what you must ask yourself is who would win in an average match up? I will refer back to my early argument with Kit Fisto and Darth Maul. Its been shown that Kit Fisto would prevail, not only because of his duelist skills, but also because of his ability to keep his cool during a fight and outlast Darth Mauls earliest onslaught of rage. Given that the Sith Inquisitor lost to a padawan and Jedi Knight (In the cartoon series) who do you really think would win? Shaak Ti or the Inquisitor? Even Asaj Ventress could be considered an Average Sith Lord. She herself held her own against Obi-Wan and Anakin, however she was later defeated by a Jedi Knight for crying out loud. Let's give another example of if a Jedi Master chose to kill: Yoda is standing in the ruins of a long forgotten battleground. Above him scavenger birds circle around, waiting for a chance to being to pick at the burnt corpses of Clone Troopers. All around him are destroyed tanks, battle droids, and droidekas. As he looks around he feels a great pang of sadness at all the lives lost, some were Jedi, some were Clones. All he counted as friends. Then, a sense of righteous judgement comes over him. He can feel light flashes of anger, however he knows he must supress those emotions. Anger is not of the Jedi. He takes a rasping breath, then..from the edges of the battlefield he sees four figures start to walk towards him. He notices who the first two are. One is Savage Opress (Brother of Darth Maul), the other is Asajj Ventress, both of her curved lightsabers in each hand. The final two are covered head to toe in black robes and body armor. Each carries a lightsaber in one hand. Yoda slowly closes his eyes. He opens them and the four Sith are in front of Him. "Master Yoda..." croaks Ventress "You know what comes next" With that final word all four light their sabers. Yoda feels a deep sense of peace, then begins to feel the light side of the Force rush through Him like a strong River Current. Opress can no longer take the suspense. He roars an animal roar and rushes at Yoda, swing heavy swings at the smaller alien. Yoda easily front flips over Opress, slicing his blade along the way. Opress stops, and falls to his knees. He is headless. Yoda continues forward with a blast of force energy that knocks Ventress and one of the Inquisitors a hundred feet away. He bounds forward without skipping a beat and drives his blade through the remaining Sith's chest. The Sith gurgles and falls to the ground. Yoda twists the lightsaber for good measure and jumps up onto the towering wreckage. Ventress wildly spins around. "Where are you?" she screeches. She is given no reply except for caws from the scavenger birds above. Some have already landed by Opress's body, picking at his flesh. She hears something drop behind her. She spins around, only to see the final Inquisitor drop to the ground holding a stump where his arm used to be. She screams and begins to run. She hears the hum of a lightsaber cutting through flesh, and knows that her consort is dead. Then she stops. "I am SITH!" she screams. A haze of red rage overcomes her. She is now out in the open. Nothing but dunes of sand around her. Then, from in front of her she sees Yoda appear. He had bended waves of light in order to make himself invisible. She raises a thin white hand and draws upon the dark side. Tendrils of Sith Lightning spring forward towards Yoda. He raises one green hand, and absorbs all the energy back into myself. He discharges it back into the sky. Then, with the Force Yoda crushes both of her lightsabers while they"1;e still in her hands. She screams as they scorch her soft white flesh. Then, she is raised into the air. Yoda wears an expression of sadness as He uses the Force to rip off each of her arms. She screams, her body refusing to pass out. Yoda then, with the sheer power of the Force..rips her body in half. So I have given an example of how easy it would be for Yoda to destroy four Sith in combat if He wanted to. A determined Jedi Master could beat multiple Sith Lords, which I have demonstrated time and time again. In the end the Sith Lords downfall is their anger, which is also their greatest asset.
