The world record is 3.47 seconds, by some 15 year old. Most pro's can finish them around 5 seconds. Although there are over 30,000,000,000,000,000 diff combo's , once you learn the algorithms to use, you can solve it easily. My method is not for speed, but to complete it. Learning the speed method will take much more effort that IDK if I'm willing to put in.
