[WR] 4x4x4 blindfolded 3:37.80 - Feliks Zemdegs

Can someone compile a list of WRs he's gotten since the last episode of CubeCast? Thank you in advance.
That sounds like it's just the ones from this past comp?
the Faz summary at the Melbourne Summer open:

3x3 single - 6.65
3x3 avg - 7.87
5x5 single - 1:01.59
5x5 avg - 1:07.01
6x6 single - 2:05.88
6x6 avg - 2:15.64
4x4 blindfolded - 3:37.80

videos will start appearing in a few hours on fazrulz1 youtube channel.

ciao!

Nice one Brest.

I just did a quick comparison of my solve to Feliks'. This isn't in any way meant to be defensive - it's just an analysis that is also helpful for me :) I have full respect for what Feliks did in this solve, and I'm sure he'd be happy to admit that the scramble was a little lucky :p

Corners were similar time to me, but my tps is slower because I think more about comms rather than doing the less-efficient but more mindless 3OP. Once I've finished relearning BH properly I'll be much faster on time, and possibly almost matching the tps.

Centres I did not execute well - more pauses than normal for me. Also there were more to solve, hence the massive time difference between us.

Edges I used all advanced r2 type stuff, so more efficient, while Faz executed in the same time spamming fast basic r2 algs. Now that my cube is actually lubed I should turn a lot faster in this stage and beat his times.

Overall I should be able to beat Faz's corner and edge split next time. His centres were too nice to beat, but overall I should at least be able to match his execution (which I'd be happy with given his huge tps advantage).
