pool.cachecoin.net says the network hashrate is 116 mh/s right now ...
My hashrate ~271k / net hashrate = 0.00233144039880279119666983471975 (A)
~1152 (B) blocks generated a day (ballparking it as I didn't have the reward formula initially but I'm still pretty close) ...
A * B = 2.68581933 CACH/day
Lowest CACH sell order on Cryptsy atm - 0.00666000 (C)
A*B*C = 0.01788755 BTC/day/rig
getprofitestimate after last nights N factor adjustment has created a 75% drop in profitability for me.
Are your estimates accounting for the drop in network hashrate since the change?
