I strongly urge all members of the speedcubing community to not participate in any Guinness record attempts. I would encourage Rafal or other cubers to not take place in their BLD record as well.
A Guinness BLD record would not be recognized by the WCA. When Guinness looks at the records of track and field, they turn to the IAAF to see who has run the fastest 400 meters time. They look to the IAAF for the regulations on what is required to set such a record.
What Guinness has done with cubing is that not only do they disregard the WCA, they put in their own rules. Using a new cube, mixed up by "40 turns" by hand? It shows a very profound level of ignorance in our sport.
Please do not acknowledge Guinness or participate in any of their record attempts. The only reason why that happened in Atlanta was because the people who gave us money to make the competition possible wanted it. I personally did not participate in the Guinness record attempt. And I suggested to my staff to do the same: to stay out of the Guinness records.
