But with CFOP, SUB20 is the "ordinary master", and the CFOP of the top master is about 1 1 sec.

Don't underestimate the gap between 1 1 sec and 20 sec. The closer you get to the peak, the harder it is to improve. In addition to learning CFOP's 1 19 formula, 1 1 sec should also remember special situations such as "nonstandard", "four-phase" and "empty slot", with a total of at least 300 formulas. 300 formulas 10 second. Personally, I think it's worth it.

You want to advance 60 seconds by the layer first method, which is actually very simple. You can definitely practice more. Of course, this is nonsense, so let me make some concrete suggestions:

1. The Rubik's Cube must be good. If it's a racing Rubik's Cube, don't buy a bargain. It must be "National Defense" and "Seal 3". There is a track inside the Rubik's Cube, and the turn is smooth. You can sell it online, 50 yuan. Don't be reluctant.

2. Technology should be standard. I suggest watching the technical videos on the Internet. Start with the basic "How to get to the Rubik's Cube" and learn step by step to correct the bad habits before. Just like practicing typing. You can't get up fast if your fingers are not correct.

3. If you want to turn fast, you should not only turn fast, but also keep up with your eyes and brain.

Eyes should find quickly, and when operating on the previous piece, eyes should start to find the position of the next piece.

Think quickly. As soon as you see the location of the next piece, you should immediately think about how to deal with it. There can be no pause.

Eyes, brain and hands are in harmony. When a novice turns, the three are "serial". Look, think, think. Eyes->; Brain->; Hand-> Eyes->; Brain->; hand ......

The master is basically parallel, watching while turning, thinking while watching, and when the last piece is done, the next piece can be made immediately.
