If anybody actually read what I wrote you woukd see the problem is much deeper than normal hashrate fluctuations. And I am not the only one. How comes a miner with 12KHs (srbminer and cast) will have less hashes on the pool after 1 week, than the miner with 11.5KHs? (Stak)
It depends greatly on the pool and the day. Somedays I average above for the 24hrs and some days under.
Nanopool is far more stable and always the same or higher hashrate 24hr average.
Hashvault ok and cryptoknight.cc pool always less.
There are soo many factors. Look at the average over several days
