How come you have the "Initial Revenue / 1MH/s / Day" as $6.27, while the page https://bitcoinwisdom.com/litecoin/difficulty gives me a 0.57 USD / day? Is there something wrong in your setting?
Indeed, it's my mistake: I forget to change the value to 0.55 USD/day.
If you want to buy an ASIC (Scrypt) for 10K USD and earn something, you have to get at least 300MH/s!
