Damn. I was hoping you were going to give me something better. This discussion has left G as my worst setup. It's not very nice for comms either.If the competitor is not touching the puzzle, they may remove the blindfold before they stop the timer. They must not touch the puzzle until the end of the attempt. Penalty for touching the puzzle: disqualification of the attempt (DNF).
[Edit: my lone official attempt was with a Stackmat and it was easy to find with the blindfold on, keeping in mind I'm very familiar since I use a Stackmat at home]
I was doing F2 R', now D2 R
