For example, I'm buying 450MH/s ETH package and starting to mine at pool A. This pool is showing avg. hash 400MH/s, then I'm switching to pool B that is showing avg. hash 390MH/s. Yes, it is a well-known fact that hashrate will vary from pool to pool, but how can I be sure that you're providing exact hashrate according to package contract? Or you're providing contract hashrate according to pool...
