One-Answer WCA Competition and Regulations Question Thread

[biscuit]

For BLD: the regulations state that the competitor must supply their own blindfold, and the guidelines recommend that the delegate check the blindfold. I know I can get one for $2.50 at the cubicle, and that's not exactly going to break the bank, but could I, say, wear a hat and pull it down over my eyes? A thin stocking cap is translucent, and obviously wouldn't work, but a thick stocking cap or a baseball cap?

Depends on the delegate. I've seen someone staple cardboard to a cloth and have it approved.

Is (1,0) off solved state on sq1 a +2? Also, how much does the slice have to be turned for it to be a +2?

(1,0) is less tha 45 degrees so it's not a penalty. Slice must be turned more than 45 degrees to be +2

This means that (1,0)/(-1,-1) is only a +2

10e4) If more than one move is required, the puzzle is considered unsolved (DNF).

If a / is a move and (1,1) is a move, then it takes 2 moves to solve that state.

(1,1) is not a move because 1 is less than 45 degrees

Not trying to be annoying by bringing this up again(lol), but the regs still aren't that clear
"Each puzzle variation must have moves, states, and solutions functionally identical to the original puzzle."
That means an corner twist is an automatic DNF, right? regardless of whether it was intentional or not

The regulations list corner twists as a defect.

The regs are clear. A puzzle is supposed to work like the original. No new types of moves added. The regs also cater for defects, meaning something that goes wrong with a puzzle by accident, of which a corner twist is an example. So no it's not an automatic DNF if you get an accidental twist and fix it, but yes it is an automatic DNF if you deliberately twist corners to help you solve the puzzle more easily.

It counts as a move for the 10 move scramble filter

 

[EMI]

Slice must be turned more than 45 degrees to be +2

No, 90°

 

[guysensei1]

It counts as a move for the 10 move scramble filter

Not here though:

Limits of acceptable misalignment for puzzles:

• 10f1) NxNxN puzzles: at most 45 degrees.
• 10f2) Megaminx: at most 36 degrees.
• 10f3) Pyraminx and Skewb: at most 60 degrees.
• 10f4) Square-1: at most 45 degrees (U/D) or 90 degrees (/).

No, 90°

Oops, my bad

On The Cubicle there is a review of the SS Big Legend that says that because it's a 70mm cube it's not competition legal. This is incorrect, yes? I want to get a large cube to use for feet, and possibly a 2H backup main as well.

If you're using it seriously it should be legal but if you use the big cube 'for the Lols' then you're intentionally getting a poor result so you can't use that cube.

That being said I had a friend who was stopped from competing because his only cube was the 18cm giant cube and they thought he was joking around but he really wasn't.

Inasmuch as I have no real chance of winning and I want to compete anyway my entire reason for competing is "for the lols." That said, I want to compete, and the only reason I would use a larger (or smaller) cube is if I thought I could get a faster time with it.

 

[AlphaSheep]

I suggest something like "If the competitor can offer sufficient proof that an ambiguous scorecard was incorrectly interpreted to the Delegate, during or after the competition, the time can be corrected."

BTW, the second that is added I would get Kit to fix a 2x2 time I got 2 years ago lol

If it makes you feel any better about it, My official OH PB should be 30.02, but it's listed on the WCA as 30.29 because I was an idiot and signed for it written as 30.2... The worst part? I was the delegate who had to submit my own result knowing it was wrong. But the guideline is there for a good reason, so it's important to stick to it. Evidence can always be altered after the fact.

I'm talking about when the competitor thinks that they are signing for a 12.97 and because everyone is subject to confirmation bias, doesn't see how the 2 might look like a 7.

E: it's really hard to completely forge a video. It's practically impossible to make a video of a 17.97 look like one of a 12.97.

During first World Championship in Budapest in 1982 were there any specific regulations about scrambling, random state, timing etc.? I geuess there were but how to check it?

Jessica Fridrich talks a bit about this at http://www.ws.binghamton.edu/fridrich/cubewrld.html.

A7c) The judge and competitor must each check the recorded result, and sign (or initial) the score sheet to acknowledge that the result is correct, complete, properly formatted, and clearly readable. This finishes the attempt.

Sorry, but this is your job as a competitor. It's not the delegate's job to look at everyone's video after the fact because confirmation bias prevented you from making sure the time was legible. They have much better things to be doing.

I think that there are reasonable exceptions that should be made. If the judge writes a squiggle and a dot or two on the sheet and you sign it, that's your problem. If it's a 2 that maybe kinda looks a bit like a 7, then they have to make it a 7, and that could destroy someone's average. I think that it should at least be allowed for delegates to correct times.

Having there be no option for times to be corrected allows for judges to intentionally mess with the way they write the times, like trying to give someone a 19 instead of a 14 so that they don't make the finals, etc.

If they do that you can tell them to fix it before you sign
