Yeah, I read about the profitability factors, but I didn't know what denominations they were using. I though both were in kH/s since cpuminer would report both as kH/s. Then I once though they both were in MH/s, since both are reported MH/s on zpool's pool status table.
We need something to let us know which algo is using which metric.
Even a simple line like the Pool Status chart: * values in mBTC/MH/day, per PH for sha256 & GH for scrypt, blake, decred, x11, quark, qubit, kS for equihash
The way I do it is to navigate to Pool, select an algo, and look at the graph for "Last 24 Hours Estimate (mBTC/XXX/day)." Whatever it lists for XXX is usually the metric you need to specify in your password. If you're really unsure about a particular algo, you can verify simply by doing the multiplication yourself (estimate * hash rate), and checking to see that the mBTC amount is reasonable for a day of mining.
