When he blasts Yoda with it 20 or so years previously, however, he intentionally wants to catch him off guard and knock the "arrogant" little sucker right off his feet, but not necessarily torture him into submission (probably because Yoda would eventually blast him backwards). When Sidious electrocutes Mace, that's the death blast, what you really get when Sidious wants to kill you. That was especially horrific (especially for Star Wars) because when he has his hands chopped off the audience kind of says, "Oh man, he's dead, no absorbing it this time." One of the best scenes.
As far as lightsaber combat though I think Mace had Sidious owned, but as soon as Anakin shows up Sidious know he's fine.
Very well thought out!
@Dunedain-- Regardless it isn't the "jedi-way" to kill unarmed oppenents. Sidious was unarmed; therefore, Mace was actually, by my opinion, treading on the darkside by wanting to "end the sith oppression once and for all". He was put in a very difficult situation. If I where mace I personally don't know what I would do. The choice was end Sidious's life and go to the darkside, or let Sidious stand trail (or possibly lose your own life) and stay on the lightside. That is in my opinion a very hard choice to make.
