The blindfold race!

It hasn't been a week yet, here's my results from last week.

3x3 BLD: 36.61, 37.85, 39.08, 42.51, 44.40 = 40.09
DNF, DNF, DNF, DNF, DNF, 48.10, 42.51, 37.85, DNF, DNF, DNF, 1:13.94, DNF, 39.08, 36.61, 56.43, 44.40, DNF, DNF, DNF
Comment: Bad accuracy.

4x4 BLD: = 6:07.54
DNF, DNF, DNF, DNF, 5:16.12, DNF, 6:58.96, DNF
Comment: Bad, but this isn't anything out of the ordinary.

5x5 BLD: = DNF
DNF, DNF, DNF, DNF
Comment: I'm surprised, 2 attempts were going fast and 2 attempts were going safe. :fp

Ah sorry I'll go add your results.

Sorry, I thought I would have time to finish them all, but didn't, so I forgot to calculate the average :) I'll make sure I do it next time :)

No harm no foul :).

Oh, and here are some 4/5 BLD scrambles. Same rules as last week.
Click to expand...

Thanks for those :). But the rules were valid for 8 (4BLD) and 4 (5BLD) scrambles.
So either we go for mean of two best of five or you add three 4BLD scrambles.

And I agree with Micael, it needs clarification if 3BLD is "most solves of 500" or "most tried scrambles of 500".
 
Define 'tried' :P

If I scramble the cube..start to memo and notice it's a hard scramble and give up..or I face some trouble memo-ing and give up..does that count as a try?

I could just 'try' all 500 this way =p
 
Ya but I gave the extreme situation. What if I put my blindfold on and totally forgot my memo and couldn't start solving. Does that count as a try?

Another problem would be how to keep track of the number solves that you've 'tried'. The only way I can think of is to have a separate notepad/document/calculator etc to record your tries, which would be a hassle.

Not meaning to attack you here Ryan, I don't even think I'll be attempting this. Just trying to help others here :)

Honor system will be in place. I assume noone would resort to such a method for a fun race.
Click to expand...

I think that is good. That's what we do here, have fun and compete mostly against yourself.
As for how to keep track of them I just put all scrambles in a spreadsheet and take (and note)
one at a time. But I do doubt that I make more than 100. I thought that was much :).
(And we have some big bld to do too).

Current standing for me:

3BLD: 75/151 best 1:14.60 WOW, not even 50% :)
I really try to go as fast as I can, so on 10-20% of the solves I just cannot remember memo.

4BLD: 7:16.60, DNF , 8:13.07, DNF , 6:55.94, 7:26.91, 9:01.17, DNF = 7:06.27

5BLD: 16:23, DNF, 17:03, DNF = 16:23

I am curious how fast your memo is, Chris. I'm wondering if I'm now more behind you in memorization or in execution. Right now, I average about 30 seconds memorizing, 1 minute solving.
Click to expand...

I've never really timed my splits before, so I figured I would try to do so on the 500 solves for week 28.

I'm at 13 attempts so far, and here are some splits from some fast and from some slow solves.

------------

Total attempt time (memo time, solving time)

1:18.28 (35.10, 43.18)
1:09.57 (31.77, 37.80)
1:26.18 (35.49, 50.69)

1:45.48 (55.06, 50.42)
1:40.68 (46.92, 53.76)
1:57.12 (42.97, 1:14.15)

--edit--
Here's a really fast DNF. I executed corner cycle (A KR) as (A LR) swapping another letter during the solve on accident, so it was only off by the one commutator.

53.67 (24.47, 29.20)

Mind sharing the tricks he taught you Chris ;)?
Click to expand...

Not yet ;) I want to refine my system first. I'm still having a bit of a time adjusting to this way to memorize. The basic method is the same, but the pacing is very different from what I was doing before. Think synergistic, though.

Hmm, looks very much like my problem relative to you is primarily execution. My memo might be slightly faster than yours! And I already know I'm almost as efficient move-wise as you, so it's all about speed of execution, not number of moves. I just have to speed up, I guess.

I have my doubts how many solves I'm going to get done this week; my time is scarcer now than it was. I'll see what I can do, though.

I already knew that your memo was faster than mine for a while now :)

As for the BLD race, I'm at 50 attempts so far. I've never done so many 3x3 BLD solves in one day, my brain hurts lol. I'm not sure if I will try to keep up this same pace throughout the week, but I do want to at least crack 100 solves before the end of the week.
 
Okay, I'll keep track here. And may I recommend: how about breaking ties based on number of successes, rather than time? Then we can use fastest single as the secondary tiebreak.

I notice that after having done a bunch of these crazy competitions, it's gotten where I'm not even warmed up anymore until I've done 10 or 15 attempts in a single sitting. :)

3x3x3 BLD:
Accuracy: 297/353 (84.1%)
Best single: 1:02.29

60/90 so far. I've been at 2/3 accuracy most of the way through, so I guess that's fairly accurately my accuracy rate. As it stands right now, when in a competition round of 3 solves, the chance that I get at least one successful solve that round is approximately:
\( 1-\left(1-\frac{2}{3}\right)^3 \approx 96\% \)

So not too bad I guess. Not sure of the average yet I'll calculate that at the end. Right now I'm just recording times.

Wow, by that calculation, I should feel pretty secure in competition! (Of course, it's not really the same in competition, so I know it's not really that good.)

For me, I have this:
\( 1-\left(1-0.848\right)^3 \approx 99.65\% \) :)

And if I want to calculate my odds of a sub-2 in a competition round of 3 solves, it comes to this:
\( 1-\left(1-0.732\right)^3 \approx 98\% \)

Obviously, I am too accuracy-focused. An example: my worst time was 5:11.23. I finished the corners and couldn't remember the edges. (This happens fairly often to me - the edges are easy so I rush through them, then the corners are particularly difficult, both to memorize and to solve, and so by the time I get back to the edges, I can't remember any of them.) But as usual, I refused to give up, started going through letter by letter to see if any images seemed fresh, a few minutes later hit one I recognized, and then very quickly remembered the rest of them. So I got it right.

May I just say this exercise is absolutely crazy? :) It's exhausting. But I think I'm improving as a result of it. Any time I notice a particular commutator execution was slow, I review it and see if I can find better. I've substituted 20 or 30 cases during just these 250 solves. Once they're comfortable, I should be noticeably faster. So I guess it's good practice.
