Tried the pool for a couple of hours with a cgminer at 260Mh of scrypt.
Average hashrate accepted by the pool was about 180Mh, no matter how I played around coins and difficulties.
Unfortunately, it was a rented asic, so I don't have access to its logs.
I'm not going to make any accusations, but the fact is that my experiment got 30% of hashrate lost for some reason...
Wow~~~~~~!!!!!!
I also had mined skein algorithm for several days in the zergpool and I had checked my real BTC earnings.
My own real BTC earnings and 24 hours actual calculating are different about 30.5%.
It's similar to your experiment. Neoscrypt and xevan algorithm are also similar.
My hashrates are 41.9G on skein algo.
24 hours real BTC earnings : 0.011253 BTC
24 hours actual calculating : 0.016191 BTC
Only pinpin knows. He always takes 30% of miners coins or 24hours actual calculating shows 30% upped.
Now I'm using ahashpool. Ahashpool shows real 24hours actual caculating with just 1% fees.
