Yet Another ETH/ETC MiningCalc (MS Excel based. Customizable. Offline. Dynamic Hashpower/ExchangeRate)

Have been disappointed with all these "constant network hashpower/exchange rate" mining profitability calculators, which just don't tell you the truth. So, made the opposite one. Customizable. MS Excel based. Offline. ETH/ETC. Hope you will enjoy it too.

Input your estimations of Network Hashpower (1) and
Exchange Rate (2) for 50+ steps in time (=up to 2 years with 2 weeks interval),
and get
Break-Even interval in days (6), Profit (7,8), ROI (9) and
minimum Coin Price you should sell all your mined coins to Break-even (10)
for three kinds of mining hardware of your choice (4,5).

The example of calculation is made using assumptions of linear hashpower growth and constant price (quite pessimistic). First rig is made of 3 RX480 (price of this rig is used as a base for calculations), the second one is 4*RX470, and the third one, D1-256Mh, is promised by Dragonfly (China).
