I don’t see any pattern here, except that the WIFs all start the same way:
KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3q
KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qZfFoWMiwBt943V7CQeX
KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qbP2K5cm35XKMND1X1KW
KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qd7sDG4F2sdMtzNe8y2U
You only need to know exactly ZfFoWMi, bP2K5cm, and d7sDG4F.
And that’s exactly the same as knowing puzzle 68 starts with 2198982662133 in decimal.
