Ok, what you are saying make sense but I personally wouldn't say I'm "making money" until after I break-even.
I would say that currently I've lost 100% of my investment.
I would say that if I sold today I'd have an estimated loss of 8.50756077%.
I would not say that I've "made money" until I see more money in my Bitcoin wallet than I started with.
All of the numbers on my "Daily Payout Rankings" show current yield after fees based on today's current GH/s price and current BTC/USD price in order for them to be relevant to someone who might be buying today.
My estimated days-to-break-even is higher because I subtract the current 110 day average daily diff increase from my calculation in an effort to make it as realistic as possible.
I'm basically calculating numbers that I believe are most relevant to me personally and then sharing them because I think others could find them useful.
If I found some other website that gave me the information I'm looking for, I probably wouldn't be posting any of this.
