Nidalee's Javelin Toss is an ability that deals increased damage the further you are from the enemy it hits at the time of contact. This ability is stated to deal 250% damage at maximum range, but sometimes it appears to be more than that.
Is the 250% multiplier a hard cap, such that added distance no longer helps after that point? If this is the case, what is the maximum distance, and is it longer than the base range of the ability?
If 250% isn't a hard cap, what would be Nidalee's maximum damage be at level 1, with starting items, assuming ally help. (i.e. Thresh's Dark Passage) on Summoner's Rift
