Yu Nakajima broke 5sec barrier!!! (4.08sec) Part2

after observing nakajima's video for a few times(maybe around 20times), i've discovered a few things about the video.


1. nakajima is not using double flip(doing a U2 using 2 fingers)

2. he don't even inspect the cube before solving it.

3. he is not using any ordinary method like Fridrich or petrus.

4. He is a MADMAN!!! Even breaking a sub-20 barrier is hard for me but he just solve it under 5 second like its a child's toy!!!
