If you look at Nakowa's actual bet data, he makes a bunch of small bets mixed in with his large bets. If you take his actual data, but just shift one colum so that he wages what he actually wagered 2 rolls earlier, then most the losses line up with the small bets and most of the profits line up with the large bets. This should be statistically impossible. So either I made a mistake, there is an error in the file, or the seed was known by Nakowa and he left a clue for us to find.
You may have found Nakowa's strategy. If he is looking 2 rolls back to determine his current bet, then shifting the data by 2 rolls might result in something like this.
