about how many blocks can i expect per day at 160k Hashes per sec?
Maybe once every couple days...
thats crazy bad profitability :/
At time of writing, the Quarkcoin difficulty is 441.12747160.
The formula for seconds per block is 2^24*<difficulty>/<mining rate in hashes per sec>
2^24 * 441.12747160 / 160000 = ~46,256 seconds per block
46,256 / 60 = ~771 minutes per block
771 / 60 = ~13 hours per block.
There's the maths for you.
FWIW, here's what it would take me, mining at roughly 605kH/s:
2^24 * 441.12747160 / 605000 = ~12,233 seconds per block
12,333 / 60 = ~206 minutes per block
206 / 60 = ~3 hours per block.
That's a 4.3x decrease in time, for a 3.8x increase in power. There are small economies of scale.
