I've uploaded my PPT slides to GitHub and added a link to my signature:

I've also added the "improver" method which builds on the "beginner" method.

How are your colleagues getting on? Any of them got hooked? If so, you should ask Marty at PuzzleStore.uk for an introducer discount! [emoji6]

In other news, still figuring out 5x5 parity, playing around with easy cases. It seems like every 5x5 solve ends in a G perm, ugh! But at least with my QiYi I can do my 3x3 PLLs, my old SS 5x5 was so locky I had to 2 look some.

They're doing pretty well. They can all solve independently using LL cheat sheets and most are on the verge of doing everything from memory. One of the guys got his first solves without cheat sheets on the train last night. He timed himself later in the evening and got 2:36 which isn't bad for his first timed solve.

I have a feeling that several guys will be practicing over Christmas. Several of the company branded cubes are missing from the office space so people are using them at home. :)

My better half also surprised me the other night after a fair few drinks in the pub. I was casually solving when we got back home and she solved it using the method that I taught her quite some time ago!
 
Still struggling with parity, but now have a WuShuang, and it's LOVELY.

As if I haven't gushed enough over the WuShuang in here, I just love that puzzle, my favorite in the collection and I'm far from being a 5x5 guy.

Quick question... I seem to remember a tutorial once talking about a website that can calculate an optimal CFOP Cross for a given scramble. Is anyone aware of what site this is and if it still exists?

csTimer will do this as well as EOLine. Bring up the Tools pane and select "solve cross" from the drop down.
 
There is also this cross trainer that I've been raving about for a week or two: http://net13.net/Cube/Cross/

There are tutorials that taught me to solve the cross relatively, there are tutorials that taught me to evaluate "good" and "bad" edges in order to multi-task... and then they pretty much left me to my own devices. This has taught me a lot of new ways to deal with cross solutions.
 
One last random thought for the day on picking up new OLLs. I'm sure it's not a new idea but using a new alg even in 3-look gives me a lot more practice in real solves. Been trying that with the square algs to handle all L cases and H for line.

I'll have to give this a go, still struggle with crosses occasionally.

What has helped me recently is watching a couple of walkthroughs on YouTube, where good cubers move good edges up to the U face to protect them. Say there's a couple of edges that are correct relative to each other, but inserting them would break up a 'good' edge.

Also setting up bad edges as good, so that after inserting 3 edges you end up with that edge just a couple of moves off. Sometimes I used to leave that edge till last, or just plan 3 edges and deal with it later, now I realise a quick L/R/whatever at the start could make it just a turn away from solved after the other 3 edges.

I think I now understand 5x5 parity, after about half a dozen solves. With 4 tredges to go I can normally see what kind of case is coming, and try to force a case I know. I use a combination of my 4x4 dedge swap (Uw RUR'U' R'FRF' Uw') and my 4x4 OLL parity alg for true parity cases.

I'm not convinced that learning further cases would significant improve my times, but I'm happy that I can solve the thing without cheating in consistently about 5 minutes. I'm sure my times will plummet fairly quickly, and I'm now at the stage where I enjoy it as a puzzle, rather than being frustrated by lots of edge cases.

I might work on an "intuitive 5x5 last 2 edges" guide for how to reduce the 10 cases simply to parity/non-parity. Pretty sure they can all be solved with a combination of 3 algs (4x4 edge swap, same with Uw+Dw' setup, and 4x4 OLL parity), with a maximum of 2 easy algs plus setup moves per case, I'll have a play...

That's a pretty common approach. You can solve all of the cases intuitively with slice-flip-slice and the OLL parity alg.

There are 15 L2E cases btw (16 including solved) - http://cubing.mikeg.me.uk/Big/L2E.pdf

Good stuff. I always do this when learning new algs.
I lied, one more random thought: no OLL alg list I've seen lists sledge-sexy as a solution for anti-gun?!
It's a really good OLLCP alg.
 
Have been picking up the 4x4 a little bit more lately and during my 3 last sessions I've managed to beat all my 4x4 PB's :)

single = 1:10.46
mo3 = 1:19.56
ao5 = 1:20.41
ao12 = 1:25.78
ao100 = 1:31.48

About time really, but then again if only I practiced 4x4 more I'd see more progress ... similarly with 5x5

Been wondering about getting the QiYi WuQue ... I'm still liking the Yuxin Blue with TC springs, but I would like something a little more stable. How does the WuQue compare to the Blue ?
 
Good progress with skewb there @Shaky Hands and @Logiqx and also really impressive OH improvement @muchacho

@JohnnyReggae - The WuQue is definately a cube worth getting and far more stable than a Yuxin Blue with TC springs. I do like my Yuxin with TC springs but the WuQue is an awesome cube

Loving your goals list @Shaky Hands Andy. Awesome way to practice to have structure to it. Hope you do not mind if I follow suit my friend :)

  • Winter Variation (I am 19 cases into the 27 case set with ones I still remembered and new cases - since Biringham Open last weekend)
  • Winter Variation Left Hand Mirrors
  • Summer Variation
  • COLL
  • Don't touch a timer with 3x3 until the end of February!
  • Parity Algs - Learned 3 new cases from Callum Hales-Jepp at Birmingham. A coupe of really interesting variants involving Half a Y perm, PLL parity, rest of the Y perm, a 2 gen OLL, a 3 edge swap OLL, a single edge swap. Learning these will make COLL far more valuable for me on bigger cubes since I will be able to turn any OLL parity (50% of solves) case into a COLL case.
  • Megaminx 4 Look Last Layer
  • Square-1 Optimised Cube Shape
 
Goals time, eh? Good idea! My goals are all aimed at July 13th 2017 in Paris...
  • Get to a point where I don't DNF FMC solves any more, and ideally average sub-30
  • Be confident that I can average sub-10 at skewb
  • Sub-30 at Square-1 (maybe learning optimal cube shape, like you, @Selkie, although that seems like a somewhat terrifying prospect...)
  • Finish learning full OLL
Those ones are the ones I really care about, but a few other lower priority ones:
  • Sub-20 at 3x3 (doesn't seem likely, but it's good to set ambitious targets...)
  • Consistently sub-1:30 at 4x4
  • Sub-45 at OH
I've really been focusing on Skewb pretty exclusively (apart from FMC) for the past month or so, and have made good progress. I'm pretty consistently sub-10 (last few ao100's) but still not consistent enough to be sure that any given ao5 will be sub-10.

Anyway, I hope you're all doing well and have a fantastic time over the Christmas / New Year break. Looking forward to seeing many of you again at competitions in 2017, and perhaps meeting a few more of you too.
