Still as per your own calculation it will take 17 days to get cashout. I hope i am not discouraging you , i just like to give my opinion to rethink on either make minimum cashout more less so users can collect their fund more quicker and you gain the reliability tag more quicker.
I promoted faucets for more than 3 years and believe me faucet users are very frequent in leaving sites , they prefer more instant cashout sites. And your competitors are already paying instant payments and they are in this market from ages.
