I did the math for hxh and this "contest" in the current arc starts when this boat departs and ends when it arrives at its destination 2 months later the boat departed in a chapter from june 2016 the chapter that just came out in june 2026 confirmed that the boat has been at sea for 12 days, so in 10 years of real time, the story has advanced by 12 days, for an average rate of 1.2 days per year if we believe this data, then this contest will be completed in 40 years
