I thought that in the way the number of day, give me the ninja in question, in the end, the time indicated is not taken into account.

I think I found. The time shown is for the remaining time, only if we drop 3 fragment of a sudden, during a sweep. Example, after winning 26 fragment in the proceeding, it will take 18 day a sweep if we harvest 3 fragments every time, has more long otherwise.
