THE BLINDFOLD RACE!

Hi cubers!​

I make this thread to do the same than in other races, like sub-20 race or sub-30race and to help you to improve your times in this category.

The idea to do this came me yesterday, when I realise there are not any "blindfolded race" and I think is a good idea to motivate you to improve in this category.

Everybody can join to this thread to improve his times if he/she can do blindfold.

The rules are the same than in the sub-20 race:

I will make categories if necessary, like sub-60 seconds or sub-120 but everybody will use the same scrambles.

I will also follow the method koreancuber use, I'll make a post with the results and scrambles and other with the achievements, like sub-1 minute and things like that.

I will wait some time (1 day or 2 if necessary) to post the first scrambles.

I hope you enjoy this time!

Average of 12? Seriously?

Maybe we could try something fancy as 'Mean of Best 2 solves' with 5 attempts.

Average of 12 is just stupid for BLD.

I agree with you.
I think the average of 12 is a bad idea.

Is it better to go slow and safe, and try for the average of 12? Or is it better to go fast and loose and try for a fast time out of the 12? How you score things will definitely affect my strategy on how I will solve. I like the idea though, and I would participate regularly.

I like the idea of the thread, but since I'm a beginner (my only success was 20mins) I can't see myself being able to do an Ao12 in a week.

If I may make a rules suggestion, how about something like this:

Best of n (where $n \leq 12$) and you must successfully complete at least $\lceil \frac{n}{2} \rceil$ of your solves. Basically, you must complete at least half of your solves (rounded up for odd numbers), otherwise it's a DNF submission. Solves may not be done Multi-BLD style.

Examples for the single BLD format:
-You solve the cube 7 times, but you must successfully complete at least 4 solves for it to be a non-DNF submission.
-You solve the cube 12 times, but you must successfully complete at least 6 solves for it to be a non-DNF submission.
-Doing only 1 solve, if it is successful, is an allowable submission for the competition.

As to some form of a ranking system, accuracy should be rewarded, and so should being fast. WCA currently rewards being fast more than being accurate, so this should probably do the same. How about two rankings to make it simple? One list ranks simply by fastest time, with no consideration of accuracy. The next list ranks by accuracy once you have attempted 6 solves or more. If you attempt fewer than 6 solves in that week, then you do not make it onto the accuracy ranking for that week. Accuracy ties are first broken by the person who did the larger number of solves achieving a better ranking, then by the faster average of all successful solves if both people solved the same number of cubes. In the event of a tie in average, fastest single (then fastest 2nd best solve, etc.) will break the tie.

How does this sound? This allows people of varying skill levels to choose how many solves they would like to do per week, and to focus on what they would like to focus on (speed or accuracy). I think multi-BLD should be separated from the single BLD, but it could easily be added if enough people wanted it.

I will definately participate if the format is adjusted.
Something like Corny's idea sounds pretty good.

I really like Chris' suggestions, the option to do just a few attempts would make it a lot more likely for beginners to get involved.

I'm in. Been practising a lot, but no where near an average of 12. I agree with the mean 2/5 idea, or maybe just best single if someone got 4 DNF's/5.

I want to try and be sub 2:30 by my birthday (22nd feb).

Well, I didn't noticed that mistake, I had thought that best of three would be a good way, like in the official competitions, but I also think that your idea, cmhardw, is very good, I'll let people to say it here.

And, what do you think about the categories by times? Is it a good idea?

This is a race, where I would have room for improvement, since my best BLD so far is 8:22.

Which method do you use for those fast times? I'm on Pochmann's old method.

Try M2 for edges, it is so much faster than T-perm edges and not too difficult to get used to: http://www.stefan-pochmann.info/spocc/blindsolving/M2R2/

Scrambles anyone? If we're still debating the format, how about we start with best of 5 and see what happens from there?

I was going to post the scrambles to do something like Sub-20 race (to put the number of the session and those things)...

Best of 5 is fine.

Javirk, I say go ahead and post what you were going to post. Clearly there is demand to go ahead and start, we're all anxious to Go ahead and post your first week scrambles, we can consider this first set that's already posted as a warm-up if you want.
