Random Cubing Discussion

Helped scramble for comp recently, and I noticed that 4x4 scrambles were purely outer layer moves for the first 20 moves or so, then the inner layer moves started to come in. Is there any reason why this was done rather than just having inner layer moves scattered throughout the whole scramble?

TNoodle uses random-state scrambles for the 4x4x4, and since the 4x4x4 solver is based on reduction, the solution to the random state ends in a 3x3x3 solve (i.e. only outer-layer moves). Taking the inverse of this solution generates the scramble, which is why the first ~20 moves of the scramble use only outer-layer turns.

Wow, didn't know that 4x4 was random state too!
 
Don't know if someone posted it already, but the appearently the SS Aurora Megaminx came out recently. Sems like it is a pre-modded SS :D I think I will order it along with the xman megaminx ^^

Wow! Thanks for the heads up. I was planning on buying an XMD Galaxy but this sounds very interesting for those of use that love the smoothness of the SS Mega but don't have the skill nor the time to mod it so this is a very nice alternative. Maybe I'll end up buying both. SS is lately calling everything they improve "Aurora", they have also produced an Aurora 5x5 which is supposed to be an improvement over the Wind 5x5.
 
Just realized this today:

God's number for building a 2x2x2 block on 3x3 is 8 moves. For a specific 2x2x3, it's 12 moves.

2 x 2 x 2 = 8
2 x 2 x 3 = 12

posted this is the wrong thread earlier because typing "random cubing" in my URL bar suggests the blindfolded discussion thread
 
That moment when an R' D' F EO-Line take you 1.2x seconds and your solve ends up being an 11.27... Total ZZ sub-10 single fail. ZBLL recognition was slow too, but I also just started learning ZBLL. Anyway I could've gotten a sub-10 with ZZ today but then, yeah...
 
Ooooh idea
someone who knows how to code well should make this:

6 degrees of seperation cubing style
A link is a competition, so examples:

2013BARK01 and 2013BARK01: 0 ()
2013BARK01 and 2016STRO01: 1 (2013BARK01 and 2016STRO01 competed together at Music City Winter 2016)
2013BARK01 and 2009ZEMD01: 2 (2013BARK01 and 2010BREC01 competed together at UIUC Spring 2013, 2010BREC01 and 2009ZEMD01 competed together at World Championship 2013)
 
Similar stuff has been done before, e.g. Blonk number, don't remember if anyone has programmed that exactly though
