Got exactly same impression, and i was mining for more than 8 hours and few more hours days before that, my account holds now 0.00127608 btc, I know someone will say bad luck.... But this is faaaar way beyond what your stats are showing, for instance same day I was mining less than 8h on clevermining and my acc balance is 0.00271781 from 22mh/s device. Waffle pool was showing 220% of ltc profitability clevermining was shwoing 139% while i was mining on each of the servers. How do you explain that? Poor hashing efficiency on waffle is my case too. Difficulty set as adviced to 8192. Any smart and logical explanation to those numbers?
