@rudyo - that math is incorrect:

1) If the Neptune delivers at 3000GH/s, what is the hashrate for each share? - 7.69GH/s

2) If the Neptune delivers at 3500GH/s, what is the hashrate for each share?  - 8.97GH/s

3) If the Neptune delivers at 4000GH/s, what is the hashrate for each share? - 10.26GH/s

Which is why people are asking why 390 shares were sold when we were told it would return 10GH/s at a 3600GH/s estimate.

@akw - My payout addresses are correct.
