Any chance of adding me to the over-40s rankings?

WCA: https://www.worldcubeassociation.org/persons/2016PETE06
Birth year: 1974

I learned the Ideal Solution as a kid in the 80s (averaged 1:30-2:00 with that method), then last year picked up CFOP and started attending competitions when my then-10yo-son took up an interest in speedcubing.

Thanks!

That's some massive variation! Basically, if I managed to plan the first F2L pair correctly, it was a sub-6, sometimes a lot faster. When I messed up, or planned only one piece and follow the other while solving cross, it was a lot slower. On some of the scrambles planning the first F2L pair during inspection seemed just about impossible. I think my cube visualization skills are still far from the level where I could consistently plan the first pair during inspection. I might do some more of this, would be interesting to see how it develops over a few hundred attempts.

I believe planning first pair in its entirety is a hard task and one that will improve with a lot of practice. Phillip Weyer only solves on white cross and I believe he can plan cross + one slot nearly all the time. Give him a scramble and 15 seconds inspection and he will close his eyes and solve the cross and a slot. This is a skill that can be beneficial to those who solve on a single colour but obviously the colour neutral will find it easier picking an easier cross to do this with. The possibilities for x-crosses definitely increase with colour neutrality. I believe Feliks can find an X-Cross in one in 3-4 solves.

I think it is too late for me to go colour neutral and at 47 I don't think I will ever catch up with my times but pair tracking can have benefit. As for the arguement for colour neutrality, did anyone see how many solvers in the World Championship final last night solved scramble 1 on green or blue?! I think for younger solvers than me maybe a switch to colour neutrality may reap benefits.

Not only some fast solves at Worlds mate but that was a lightning quick update too :cool:

I have just found your excellent guide @mark49152 which I will be using now. Great work mate :)

I also created something for PLL recognition a couple of months ago. It uses my existing framework for online algs and isn't bad as an interactive resource.

You can change the way the cases are listed (groups, grid, etc) and clicking on individual cases gives you a lot of additional info.

Technically it is still WIP as I was still reviewing and tweaking my wording but life got too busy so I made it public.

Oh yes... grid mode is quite nice as a self-test on a desktop / laptop as you can hover the mouse over the case to see it's name and you can click it for full details.

Cases which can be easily confused are typically in the same column.

About 2-sided recognition, I know the cases in theory, but haven't quite figured out how to best approach the subject in fast solves. In particular, if the 2 sides you see have no pairs or headlights, what is the quickest thoughts process to find out which case we have? What is the first thing your eyes would look for when you encounter a case like this? My approach is to immediately look at a 3rd side...

I think this falls into the bookends on Mike's (@Logiqx ) page http://cubing.mikeg.me.uk/algs/2spll.html in the last two sections or the no headlights, no blocks on Sarah's site https://sarah.cubing.net/3x3x3/pll-recognition-guide#section/adj-cp-e

These will be the hardest to learn to recognise quickly but can still be differentiated in various ways as shown on those pages. Like much in learning any new skills, once learned I will expect a rise in times until it is reinforced through repetition but I am eager to ensure I use it for all cases.

That's exactly the approach I tried to take in my guide. Catalog the easy cases with blocks visible, and define the other colour patterns to look for when there are no or not enough blocks.

Generally the advantage of two-sided recognition is that you pause less, even if you do look at a third side. For example, I might immediately see the two sides facing me during the final move of an OLL and know I'm getting an R-perm. Then I have to AUF to execute the R-perm and after the AUF I can see a third side. Unless I've screwed up, that third side confirms I was right, but by this time I'm already set up for the alg and starting to execute it.

https://www.speedsolving.com/forum/threads/two-sided-pll-recognition-guide.41108/
 
CP recognition also helps prior to executing an OLL algorithm.

If you recognise corner permutation prior to solving OLL you will know what subset of PLL you'll get. It makes PLL recognition quicker when you anticipate the CP and you can figure it out whilst executing the OLL itself.

I sometimes use it when I get a COLL case but opt for my standard OCLL to avoid a pause. Sometimes I'll figure out the CP before I reach the PLL.

I think advanced solvers do it very often.
 
Another progress report:

We went camping this weekend and I spent several hours under the pine trees relaxing and solving. I've got 6 of the 7, 2 look OLL algorithms memorized now and I've forced myself to always use "pair up and insert" F2L. I probably solved the cube a hundred times or more over the weekend and just timed myself today. My move to F2l has slowed my times quite a bit but that's expected. As I start to see the shapes and develop better pattern recognition I'm sure my times will drop again. I'm currently back up in the 1 minute 20 to 1 minute 40 range. I'm sure I can get my times back down into the low 1 minute range or even sub 1 minute as my F2L gets faster.
 
Managed to get a PB 7x7 single on film. Think this is my first sub 5:10 and promising progress. Last year I did not qualify for 6x6 or 7x7 at UK Championship as you needed an official sub 4 min mean for 6x6 and sub 6 minute mean for 7x7. Been looking at comps this year and hopefully Guildford Open will have 6x6 and 7x7 to give me the chance to get below if the same qualification times are used this year. Hopefully I can get a sub 5 minute solve on film soon.

7x7 Single 5:03.87

 
Not much new to report here, though I did land an Ao5 under :25 this past week. :27 seems to be the new norm if I'm warmed up and having a good lookahead day, Ao50 still right at :30 but I expect that to be beaten next time I do one.

I'm taking about a week off from timing my blind solves. Too many repeated issues with flipped edges/twisted corners during memo. On the edges I think I'm getting distracted and looking at the wrong sticker due to my fingers playing twister; on corners I've started a stupid habit of memoing the sticker at R instead of A at the beginning because I look back there first to identify the piece :eek:. Should just be a matter of practice as usual so I'm giving specific attention to these problems for a week or so without much timer pressure.

I haven't attempted 3 for mbld yet but will probably start giving it a shot soon since I landed 2/2.

Great pics @Logiqx.
Did you get any footage of Bill Wang's solves in the 4x4 finals? He was asking on Facebook if anyone had them.
 
Great posts everyone. I use another PLL recognition tool but the premium version which is obviously better. This is from Feliks' site https://www.cubeskills.com/tools/pll-recognition-trainer
He also has a blog on colour neutrality. I tried it for a while but I think I am too old to switch now. @Selkie

@Logiqx would it be possible to add me to the over 40s competitors' list please?

@Shaky Hands @Logiqx So cool the picture with Erno!!
 
3rd at-home attempt at 5BLD (plus 3 official attempts), off by 1 flipped edge. I must have memoed it as a flipped edge when it was actually already solved, because I'm positive I flipped it during execution. Time was 33:14. I'm gonna try one attempt per month.

Some PB's in the last week or so-- smashed my 3BLD from 1:32.69 to 1:32.50 :), then a few days later really did smash it to 1:23.29. That one will probably last a while.
Had my first ever 3x3 sub-18 ao5 with 17.80, then beat that twice, down to 17.44. First sub-19 ao12 with 18.76. Still too inconsistent for big averages, but did get first sub-21 avg of 30 and 50. Slowly but surely creeping towards sub-20.
