This is a world record by 35ish minutes. Done with reduction method, on qCube (on Chrome). The video is sped up to 10 times. As always, this was done in one sitting without any macros (using one key to apply more than one move).

Some information:
- Exact time: 1:11:48.929
- Seconds per piece: 1.988
- Moves (not counting handshifts and rotations): 13733
- Moves per second: 3.19

This is my second ever 20x20x20 solve, and a lot has changed since the first one, which was a bit over 4 years ago. Back then I was using my IsoCubeSim program, controlled with the keyboard, and I used a centers last method, which was the easiest fast method using that control scheme. Since then, Ryan Heise's keyboard controls were created, optimized, and extended to large cubes, and the hi-games, jfly, and finally qCube simulators were created. So now I can solve this on the keyboard, with this unorthodox perspective, and with the reduction method, which is almost certainly fastest for keyboard cubes. A lot of interesting stuff has happened in these four years!

Anyway, sub-hour is possible. I'd need to shave off around 16% of the time, but I think it could be done by improving at finding center pieces, especially in the middle rows where counting is difficult. I'm getting pretty good at handshifting and made relatively few mistakes this time, so that's not really an issue. I don't really feel like solving this again, though... Maybe in another 4 years ;)
