Are the daily rate based off the reported hashrate (client-side) or calculated from submitted shares on pool-side. I suspect it's based of client-side hashrate as it doesn't seem to tie up with what I've earned.

And is there a way one can finetune amd cards for ETH and store that value? I don't want to be smashing the -dcri button every time your miner chooses to restart or changes from one ethash algo to another.
