Reasons why I have very reluctantly left this pool:

1. The hash rate as shown by the pool is sometimes substantially less than the hash rate shown by the miner and I have no explanation for that, and don't know whether that means the miner is earning less than it is capable of.
2. I have 6 miners, so I need 6 web pages open to monitor what each miner is doing. I could lump them all under one address, but then I cannot see which miner is playing up.
3. I coincidentally joined the pool at a time BtC was taking a dive. Any increased profit there may have been from the pool were offset by BtC losses.
4. No facility to counteract 3. above by selecting a scrypt coin payout, after all I am using scrypt miners because I wanted to mine for scrypt coins.
5. To sum up, I have no evidence that I'm better off with this pool, and the statistics are lacking or too difficult to gather, to enable me to get a good comparison.
I suspect this pool does have benefits and will try it again at some time in the future.
