How much mana are each arrow of mana regeneration?

For health it's easy, one arrow up or down is 2hp/second. But for mana I can't seem to figure it out.

I'm guessing here, so I hope someone can tell me the right information:
Arrows Of Mana Regeneration / Mana A Second
3 arrows / 1mp/second (1 mana every 1 second)
2 arrows / .5mp/second (1 mana every 2 seconds)
1 arrow / .25mp/second (1 mana every 4 seconds)

Am I off? Is it like 2 arrows is .75mp/second or .66mp/second? I don't have a stop watch so I can't time it exactly. Does anyone know the exact mana per second? Also for 4 arrows and more?

Thanks.

One arrow is .33 mana regen, so 3 arrows in one mana a second. 2 arrows is .66

Ah nice. Thanks.
