Actually the official SW site clearly states it is debatable:
That being said, I do believe Mace won the Saber fight (as per Lucas's comments). I just don't think Sidious was as helplessly defeated as he made out, after the Saber fight finished, (also as per Lucas's comments about Faking Weakness).

The reason they don't or wouldn't say palpatine threw the fight because it's not the main focus. Look at everything that happened. At the end of the day Sidious won because who was thrown out the window? Who became the emperor? What happened to most of the Jedi? Did Darth Vader become Darth Vader? In the grand scheme of things deciding who won the fight is really insignificant due to all other events that happened. Who "defeated" yoda? So at the end of the day Sidious throwing the fight or windu winning legitimently is insignificant. I haven't avoided your questions.
You do understand how books work correct? Describing his plan is describing his plan, on how he planned on fighting palpatine, that doesn't translate to windu legitimently winning. Books go into far far greater details than movies and add in a variety of Inge to make the book interesting and to keep the reader on their toes. I would think this would be really simple to understand. Also in throwing the fight Sidious would have to fake lose. Windu wouldn't knew this he's thinking Sidious is trying to win, and the author keys on to how that would work.
Adding the commentary really doesn't tip the scales at all. Now while we are at it their are a few things you've been evading. If Sidious didn't throw the fight than why did he go for kolar and tin first instead of going for windu? He had the speed and was able to attack at least one before windu was Abel to successfully parry anything, so why go for the weaker ones and not the you know I leader who in this case is the best. Also the novel says Sidious was bending his share and windu was chocking on ozone from his own saber and didn't have the strength to fight his own saber. Why would Sidious just stop if he was faking weakness, if he wanted to kill windu at that point why stop, he had it. Also Sidious is canonically proven to have two saber sin ROTS why not take the second one out and continue with round two. Another question, why would Sidious, having windu at sword point not lunge for his heart? He was one inch away from his chest and windu was starring at him with surprise/fear on his face and Sidious never lunges. Also he never uses his force powers during the battle as of the movie and we have seen in all his other fights he uses his force powers with the exception of his battle with yoda however that was an entire battleground and you yourself have just stated that windu used shatterpoint to figure out Sidious would need to slow down. That shows windu isn't the better fighter and wa only able to do anything due to the environment. So it's yiou who really need to reconsider your stance on the matter.

If it was apparent then there wouldn't be this big of a debate. Again that raises the question of why go for the weaker Jedi if he could have killed windu just as easily if he won't for him first being the faster of all the other Jedi even windu.
We have already gone through this. Dave filoni has stated he had a second in ROTS and he had one during his battle with yoda and he is a confirmed from 6 specialist, in fact he's a confirmed master of all seven styles, so he would have great skill with jar Kai and would have a second blade.

First of all why do all of your comments start off with something border line belittleing. Personally Lucas doesn't really care. He made the movies and now he's retired in bliss. But to that your argument that's is just what I believe is a possibility. Well according to the poll in Quans thread for this topic, 14 people are on my Side of thinking while 8 are on yours whcih shows that a vast majority is not on your side. Also the vast majority of the world is possibly split as it has gained so much attention and debate it would show that this is a popular belief for the movie. If it were made crystal clear than there would not be this large debate. If a 5 year old saw that he/she wouldn't even be worried with that question, they would be so,concerned with the colors of the blades, and Sidious Lightning. Again if the vast majority believe this to be true there wouldn't be this large of a question of it. Also you don't look at the Sidious side, just your won which is being heavily biased.
Do you honestly thinks he gives two shits about windu bulldozers who don't look at entire scenes. Well the reason he wouldn't feel like is because he no longer owns the rights and he is enjoying his retirement and money. This paragraph is really you repeating the same thing over and over again being a rather annoying child about it. If it were all set and done there would not be this large argument. Stop being a biased child, look at all evidence, think about it, look at it from another person perspective, then move on with your life. You being a biased almost bully isn't helping you or anyone else, just making you look stupid.
In conclusion this entire post is based on you being biased. I've answered your questions now answer mine.

No that's not the point. The point is Sidious was goingall out from the start and showed in both the movie and the book he could have taken windu out first if he chose to as windu wasn't in vaapd yet, and he attacked kolar/tin before windu could react.
I've already proven to you. Just because you choose to ignore it, that's not my problem.
Khan kills people by shooting them. He kills yoda by shooting him. Yoda doesn't defeat people by ragdolling them so you made up some shit because you're ignorant.
And the Official Site is actually more Official than Lucas now, given that Lucas isn't in charge anymore. And the Official site makes it perfectly clear that Windu's "victory" is questionable. End of.
That said I don't agree with EmperorSidious that Sidious was holding back throughout the fight. And I do think Windu legitimately disarmed Sidious in that fight.
But "defeating" Sidious is a whole different thing to disarming him, as Yoda can tell you.
