no idea. but here is the one about sidious and yoda.
For the curious, Gillard does not reveal any Jedi who has achieved level ten. The highest is nine, occupied by a small number of capable sword masters, including Yoda and Darth Sidious. At so high a ranking, it comes down to individual fighting styles as well as the circumstances of the surroundings that make a difference.
Ah, but in the Star Wars novelization, Mace Windu (although according to Gillard) knew Vaapad. In Vaapad, he could sink into a sort of trance while fighting, basically untouchable. But Yoda lost to Sidious in the Senate Chamber due to the fact that Sidious gained the high ground in a Force Battle.
I dont know what that has to do with anything, but..
He couldn't defeat him in that current situation of course not, there were stormtroopers all over the place, and Yoda doesn't have a 500 inch vertical to get back on the pods. The fact remains that the novelization s less canon than the movie itself and in the movie it was a complete stalemate with Sidious always having the higher ground.
