Today I decided to take out my calculator, and: at 7% a week, to generate 2,4 BTC last week you had to deposit around 35 BTC. A loss which would be covered with about four weeks of no dividends, if net mining revenue is 8,5BTC a week... which is not so bad as I feared, 4% is enough to take the risk after all

But are my calculations right?
