Insane, carried me to my 59:57. I timed this against a normal Dooku from one of my previous PBs, and the new skip saves 60 seconds compared to the normal fight (if you get the barrel and out of bounds on the first throw).

White text on the intro crawl disappears at 35:27.26, and the status screen wipe starts at 37:07.96, making this a 1:30 Dooku.
