Your calculation are correct but you going by what's on the pool right now. MELY is not running their servers at full capacity just yet, so your numbers in the formulas will be greater than what you've put in. Been here for awhile now I seen the beta testing and what the servers are capable of. 1 th/s server is capable of producing 1.2 th/s Their servers are a 1 th/s +/- 10% MELY putting 100 servers together should increase the hash rate not keep it the same. That's why 100 servers will be a big deal once MELY PR's it
