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?
Block target is 15 minutes which equates roughly to 96 blocks per day. A majority of which are PoS, not PoW.
We're sitting at 1 mined block (PoW) in 14 hours. So your calculations are way off.
