Ohhh this pool is so fishy. My hash-rate shown there is about half of what I'm actually hashing (6000kh/s instead of 9600kh/s). Also the payout I have in the last 8 hours is equivalent to 3.11 LTC (I took unconfirmed balances into account), while I should be getting 12LTC/day at my speeds. So there's 3 LTC short, even though this pool mines at equal to or greater than LTC profitability.
Yes they're skimming my shares, that's for sure. Must be that "time based PPLNS".
Everyone take note of this as a good example of how not to ask for help.
Your hashrate shown on the site currently is 9292 KH/sec. It's a 10 minute average so looking at it right after we switch coins will not be very accurate. There is also a 1 minute average available on the "My Stats" page.
As far as your payouts, I looked at your payout for the last LTC block and it was 0.466583 LTC for 339776 shares. I submitted 48256 shares and received a payout of 0.0669348 LTC, and my hashrate today is around 1350 Kh, because I've been testing PPC on one of my 7970's. (Normally it's about 2Mh).
339776/48256 is 7.04, * 1350 = 9504. So it seems that your payout (for that block at least), was reasonably close to what it should have been for your reported hashrate.
All of the payout details for every block we mine are available on the site, if you feel there's a problem with a particular block, please let me know and I will investigate.
