Older cubers discussions

Been practicing 2x2 and 3x3 for comp tomorrow. Usually 200 2x2 solves and 50 3x3 solves per day. I didn't spend much time with Ortega before realizing I'd be better off sticking with layer by layer. My last 2x2 session
number of times: 100/100
best time: 2.75
worst time: 13.03

current avg5: 6.57
best avg5: 4.62

current avg12: 6.49
best avg12: 5.51

current avg100: 6.60
best avg100: 6.60

session avg: 6.60
session mean: 6.62
My last 3x3 session was 23.56, which was PB for mean of 50. Going to be really annoyed if I don't get sub-10 and sub-30 at comp.

Also did a few MBLDs. Had a 5/6 which is PB for most cubes solved correct, but it was so close to 6/6. Executed FL edge instead of BL on the last regular target (not counting flipped edge targets) of last cube.

Wow! Congrats. That's a nice Ao100. You are a full second faster than I am. That's a clear motivation for me to improve ;)

I have continued with 2x2 and it looks like paying some attention to other events (instead of just practicing them just a bit in between 3x3 sessions) is paying off. I am now clearly below 7 seconds average with Ortega, after a 500 solve session.

single
best: 1.56 --> This was a stupid scramble with a 6-move solution but PB anyway
worst: 12.21 --> Still some sup-10s, but only when I mess up the solve, otherwise most of them are 4-7 seconds.

avg of 5 best: 4.84 (σ = 0.16) --> First sub-5 Ao5. Nice!
avg of 12 best: 5.71 (σ = 0.75) --> Also first sub-6 Ao12.
avg of 50 best: 6.39 (σ = 1.01)
avg of 100 best: 6.51 (σ = 0.96) --> Almost half a second of improvement!

This is the scramble for the 1.56. Can you see the 6-mover?

464. 1.56 F2 R U R2 U2 R2 U2 R2 U'

I have to say I just saw the OLL skip and was expecting a T or Y perm. I was so astonished by the PBL skip that I wasted some tenths before I stopped the clock. Otherwise it would have been close to 1 sec. Well, 2x2 singles are dumb anyway. I consider the real 2x2 PB to be the Ao5 at the very latest.

EDIT: It's in fact a 5-mover, probably not legit by WCA regulations. Or is it just 4 moves for 2x2?

Looks like a 3-mover to me. z' R2 U' R2
Very nice improvement with your 2x2 solves.
My PB is 1.48 on a 4-mover. Scramble F' U' R' F' U F' U2 R' U'. I don't know what WCA regulations are for minimum length.

Yeah, my doubt was whether the R2s were counted as 1 or 2 moves. I counted them as 2 but if they are to be counted as 1 then the scramble is not legit. I checked WCA regulations and I found this:

4b3b) 2x2x2 Cube: The (random) state must require at least 4 moves to solve.

Nice scramble by the way. Did you see the full solve in inspection?
x' y F' L' U' L :)

EDIT:

12a1) Face Moves:
12a1c) 180 degrees: F2, B2, R2, L2, U2, D2.

12a3) Outer Block Turn Metric (OBTM) is defined as:
12a3a) Each move of the categories Face Moves and Outer Block Moves is counted as 1 move.

So it looks like it is not a legit scramble (just 3 moves), which is strange, as it was generated by csTimer in WCA 2x2x2 configuration.

What else is up?

I've not had so much time for cubing this past week. I've been offered a new job and handed in my notice at work. I'm also in the process of buying a new house and trying to understand the impact of issues reported in the survey. Busy, busy!

I did find time to do some timed solves today. Nice to get some PBs... possibly inspired by Marcel!

Great to see the wide variety of things other oldies are working on.

My goal (not sure how realistic it is!) is to get at least singles in all official events. The ones I don't yet have are:

  • 6x6
  • 7x7
  • 4BLD
  • 5BLD
  • Square 1
  • Feet

Of those, I'm going to be attempting feet, Square 1 and 4BLD at the upcoming UK Championships. I don't hold out much hope for 4BLD, but I do hope to beat the hard cut for the other two (5 minutes and 2 minutes for feet and sq-1, respectively).

I started trying feet solves a few weeks ago, and have done some proper practice this past week. My best time is around 3 minutes now. My biggest hurdle (apart from just doing U' and D moves) is the lack of muscle memory meaning the majority of my OLLs and quite a few PLLs are not possible for me. I just started trying to relearn some of the important ones (e.g., 2-look OLLs) for feet.

I quite like square-1, although I have absolutely no idea how people solve it so quickly. The first stage (cube-shape) is still quite an intuitive, slow process for me, and then the rest of it I guess I'm using quite inefficient algorithms. My best time is just over 1 minute but I'm typically more like 2 minutes.
 
And a lubing tip for the older folks:

Two or three drops of Pjur Body Glide *ahem* personal lubricant will make any slow cube super fast. It's also good to know that it's non-toxic and non-corrosive. Just in case you were wondering, of course.

Haha. I might find some other things to work for my cube now that you have me an idea.

I guess with your PBs we can overlook your limited cubing. Good job on those btw!! Remember, houses and jobs come and go, but cubing is forever.

I wasn't expecting that...I thought this was going to be the answer:

I've never tried it, I don't suppose it would help my dodgy look-ahead, anyway.
 
Incredible session this morning. I've made 10 bld solves and then few warmup solves. I had to make something in the garden and I was back I've made solves breaking my pbs in ao5 and ao 12. It was amazing feeling - my cross was good and fluent, I was finding first f2l very quickly and my lookahead was very good.

Comp thoughts & results -- 2x2 is hard with nervous fingers.
Median age was probably about 12, but that's ok. Still had a couple of parents compete and some 20+ year olds. Supposedly more parents are going to compete at next comp, so that's cool.

2x2 -- Screwed up 3rd solve, couldn't find a starting point and inspection time was running out, panicked and started with no plan. 4th solve got a +2, not sure if I did wrong AUF or cube turned when I dropped it. So kinda slow, but did get sub-10
(7.96), 9.23, (16.05), 9.58, 8.68 = 9.16

3x3 -- went smooth, a couple of minor errors like F2L pair in wrong slot, but nothing major. Much better than my previous 45 avg
25.26, 26.61, (23.23), (27.76), 25.00 = 25.62
