The calculation up there assumes the champion has 0 mana other than from the staves.

Break even point is a bit under 300 mana.

Assuming you could somhow get the full 1000 mana stacked by that point, I think every chamion with mana reaches this by level 4 or earlier (Ashe had the lowest mana that I could quickly find)
