My bad, misurdestood that.

I think what Sei is trying to say is: when did the Warring States start as an era? It didn't start when Madara and Hashirama were kids, it clearly had already existed for quite some time by then.

In my opinion, it can range all the way from Hagoromo's death to the founding of Konoha, since I don't see what could have been different during those times that deserved to be highlighted as a different era. Though, if other eras did in fact exist in-between, I'd wager the Warring States Period probably lasted roughly the same time as the its real world counterpart in feudal Japan, which is approximately 133 years.
