In my humble understanding, he -as many others- thinks that there is a pattern and he tries to predict it. But it's as simple as the puzzle creator said: THERE IS NO PATTERN. The puzzle creator would not be so foolish to use a predictable pattern, would you in his position?
There is not pattern, that's true. All next puzzles are just random numbers masked with leading zeros. But if you use math you can narrow down the range of searching by 50-70% for 90% of puzzles. I've formula what shows that I need to compare only 9 600 000 000 000 000 000 addresses with address for puzzle #66. I need someone who can help creating a script for that because I'm not into IT much. I can rent hundred 4090 for that and share with reward.
