New Rubik's Cube Speed Record

From The Daily What: 15-year-old Feliks Zemdegs set a new world record at yesterday’s Kubaroo Open in Melbourne by speedily solving a 3x3x3 Rubik’s Cube in 6.24 seconds.

Zemdeg is responsible for setting the last three world records, despite having only been “speedcubing” since 2008.

I can solve one in 50 secondish, if I'm a bit lucky. I can't for the life of me see how this is possible. I always hesitate slightly when trying to recognize the last layer,and which corners are right and wrong, which is holding me back. Perhaps, with some intenste training , I might be able to push my time down to 30 seconds or so, but under 7 seconds? thats insane..

EEehhhhhhhh???

He didn't SOLVE it in 6 seconds.. he looked at all sides of it for 6 seconds, formulated the pattern to rotate it, and then took 6 seconds for the act of rotating the sides to match..

MEAN while there was no standered of determining if the number of rotations was consistent. Speed records only work on level playing grounds, but if there is no guarantee that one cube uses the same amount of turns as another, you don't have a fair playing ground.

In competitions, cubes are usually mixed with random patterns to ensure maximum mixing. I'm not sure about the rules for the so-called inspection time, but as far as I know, Its far more timeconsuming and difficult, if not impossible for a human, to see the solution during inspection. you can plan a couple of moves, but the majority is made up as you go. A typical speed-solving is maybe around 30-50 moves. there are also "fewest moves" competitions, and I believe the world record is something like 22 moves.
