[Official] 4x4 38.96 of 5 Erik Twente Open 2012

[Erik]

Managed to prevent OLL parity during centres.
Times: (38.40), 39.19, (40.22), 39.09, 38.60 = 38.96 average
Method: avoid OLL parities and Yau method

 

[aronpm]

Nice

 

[y235]

How do you avoid OLL Parity during centers?

 

[Faz]

How do you avoid OLL Parity during centers?

It's intuitive. You'll pick it up one day.

Nice average Erik

 

[rubiksarlen]

It's intuitive. You'll pick it up one day.

Nice average Erik

How often can you prevent it in a solve? Your WR avg had like 3 OLL parities, which slowed the times a lot..

 

[Julian]

avoid OLL parities

Edge cycles? How long does that take you during inspection?

Yes I'm not much faster nowadays, I don't have time to practice. Times are just better cuz no OLL parity anymore ^^

 

[YYT]

That's amazing!How could you make it?

 

[antoineccantin]

9th in the world yet you only got 3rd

 

[Sillas]

Congrats, Erik. Great average, epic OLL parities avoided.

 

[That70sShowDude]

3rd in the round w/ a 38.96 average

mind=obliterated

 

[masterofthebass]

3rd in the round w/ a 38.96 average

mind=obliterated

Thats what happens when people start using Yau

 

[Kirjava]

*mwah*

 

[schuma]

I'm also curious about the method. I wonder if Erik or Feliks would like to share it.

 

[tx789]

maybe they keeping it a secert


nice avg

 

[ottozing]

i think avoiding oll parities is the new zeroing (if you know what i mean).

 

[Reinier Schippers]

Getting lucky is not a crime right erik?

(lol avoiding parity)

Scramble with White on U and Green on F
Move counts are estimated using [wiki]STM[/wiki] & [wiki]ETM[/wiki]
All notation is SiGN
Wide and slice move examples using SiGN notation: alg.garron.us
Rotations may not be actually what was performed
Moves and rotations in ( ) are executed simultaneously
"F2L" in the statistics refers to the four courner-edge pairs only
Thank you to Erik for the scrambles

Thanks Brest! Now only to find out how to avoid those OLL parities.

that was just a little joke Getting lucky is not a crime
