For some reason I can't get this to work, I've tried like five times. I don't even get the blue center in the beginning and if I do the whole solve I end up with a totally scrambled cube?! Is it something wrong with me, or is the scramble/solve messed up. Would like to be able to get some tips from this solve.

Worked perfectly for me, maybe you just scrambled wrong?

Your cube should look like this:

5tps wow! How many tps were Faz one.

Watching that solve I can't imagine there is much more to give. Practically perfect. Sub 30 will happen, but it's gonna be hella small increments from here on in. Amazing matz, absolutely amazing.

According to this, the 30.28 single was 5.22 tps.

I noticed in the reconstruction he actually broke the WO edge and remade it. Could have shaved some milliseconds off there!

Faz had a 31.59 Double Parity in World Championships. OLL Parity at 24.xx or so. Nakajima has had a 4 second PLL on a 32.xx as well due to a lockup as some examples. A few others have had similar stuff happen so I wouldn't expect for it to be too far away!
