Scramble Checkers / Require scramblers to sign score cards #214

Closed sarahstrong314 closed 4 years ago

This idea was brought up by Raymond Gaslow (Torch) in this thread on Speedsolving.com.

It's a simple idea that would help prevent misscrambles by giving scramblers an incentive to scramble correctly, as well as an opportunity to double check that they're on the correct scramble.

It would also allow delegates and organizers to know which scrambler scrambled each attempt.

This is the first I've heard of scrambler lists, but they sound like a good idea to me.

So, as the use of scrambler checkers is not always assuring correctly scrambled cubes, this is another simple and easy to implement alternative.

Can we unofficially gamify this and highlight people who've scrambled often without causing incidents?

Hm, sounds like a fun idea, but it's difficult to implement. Making "no incidents" an indicator for good scramblers is probably unfair: doing 500 2x2 scrambles with one reported misscramble isn't worse than doing 20 5x5 scrambles without a misscramble.

This "scrambled without causing incidents" should read "scrambled without causing incidents that were caught", or even "scrambled without causing incidents that were caught during the competition" (as sometimes incidents arise after analyzing video footage at home). Now if you put it this way, it doesn't sound as cool achievement anymore :)

Rubik's Cube Pune Open 2016 Delegate Report by Nikhil Mande:

A big incident here. The square-1 single national record was broken at this competition. The scrambler was a reliable person, and an ex-delegate who had shown up just for an hour to meet old friends. Because of this, I didn't bother checking whether the scramble was right or not. Later that night after the competition was over, I asked the competitor for the video which he gave me. The cubeshape was same, but the scramble wasn't. I also sent him the scramble to find out where the mistake might have been since I don't own a square-1 now. Within a couple of minutes, he pinged me back saying that somewhere in the scramble, a (0, -3) was done instead of a (0, 3). I'd be sad if the time is changed to a DNF. The actual scramble is below. (0, 2)/(-3, 0)/(0, 3)/(0, -3)/(-5, -2)/(2, 0)/(6, -3)/(-3, 0)/(-5, -3)/(0, -2)/(2, 0)/(-3,-2)/ Please give opinions on whether the time should stand or not.

I'm convinced that we need to institute mandatory scramble checking (or at least forcing the scrambler to sign off on the score card that they checked the scramble) until we get scramble accountability under control. In this case, even a reliable person made a mistake, but it's a mistake that we could have guarded against.
