You're using one month to estimate an APR figure??? On a market where diff rises at an exponential rate?
You're the one picking November and that ridiculous 5-6PH number. LC will already have been mining for months by then.
And yes, I can calculate an APR value for the given profit of a given timeframe.
Let's have some chips working first, since their big value is on getting hardware running sooner than later.
Since they are planning to start mining within 5 days, they have working chips already.
