In my case it was roughly a loss of 50% as the unexchanged went from 0.17BTC to 0.05BTC while the exchanged went up by only about 0.06BTC. Disappointing conversion rate however still the eventual payment will be the highest in weeks.
no lost for me when my unexchanged dropped from 0.066 to 0.022 / I got a little more than 0.07 today - my second highest day in 2 weeks here.
My mean is 0.045/day with 4.4 MH/s (with some maintenance on my rigs and connection issues I was probably, on average, more around 4 MH/s during these 2 weeks)
It's far better than what I earned mining litecoins only and much simpler than exchanging myself the coins mined on different pools.
Till the first day I'm happy to mine here.
