You won't get with this hasrate increment..Also this was luck and cannot be calculated this way. It might happen you find 2 in next few hours and next 48 hours This doesn't mean you are mining one block per day.
Huh this one was really good, i think we need to focus to current price and exchange.
This is true my best mining gains were from solo mining, everything else is projected incomes and with constant hashrate increasing this becomes overestimated prediction. But pools are needed as assurance.
