I just started mining 24 hours ago on btgpool.pro and am also not getting near the coins compared to my hash power.
My 3 hour average is 1.12 Ksol/s, which is also on target with my miner stats and has only been varying by less than 10% in the last 24 hours. I currently only have 0.0111 when the calculator says I should have 0.0266.
I think I'm going to switch over to Vertcoin soon...
Its not the coin, its the POOL you are using. Many pools steal 30 to 70 % of your mined coins, mostly the "free" ones take 50 to 70% of your coins, you don't even see it.
