the creator doesn’t involve any pattern for create the address puzzle, he's just make it randomly, but per bit of range has "sequence" IMO ("Nowadays people say in range of bit), since the bit is larger the 10% is like 1000000% for that bit.
he just make us curious, with his formula to make the puzzle.
don't delete this, i dont mean to make spam on thread, it's just clarifying THERE'S NO PATTERN.
Are you looking for eggs, the creator himself here in this thread said that there is no logical pattern, that they are random, you will be theorizing aimlessly, wasting time.
