CFOP Blindfolded

Yes, the term for it is "speedblind" and it has at various times over the years been quite popular. I'm not sure what the UWR for it is nowadays, but I wouldn't be surprised if it was close to if not sub-10 seconds for a single. The time counts only the solving time usually, but there are variations where you count the total memorization and solving times. If I remember correctly, a few years ago, a sub-10 minute time was considered quite good, but the times are probably even a lot faster than that today.
