Oh Zpool. I like you very much but you make it really hard to write software that auto-switch to the most profitable pool (like MinerControl or my own software). Here is an extract from the values returned by your API for the neoscrypt pool :

This one abhorrent value (5375 BTC/Gh/day) screws up everyone that switches based on an average. I think it is default behavior for MinerControl (it definitely is for my software) to average the last 2 hours values to make a decision. This single 'error', makes everyone switch to you for the next two hours. Even if you are not the most profitable.
Guess I'll have to work around that and hope it is unintentional.
That must have been from UFO. It was diff blocked for a day or two and so when a block was found the chain, well, that would make the diff drop super low to allow it to catchup with blocks and thus making it jump the profitability. I would expect that it would report the same on all pools with UFO in their mix...
