some observations after another 24 hrs mining here. I had moved off to another pool previously, but came back and had a balance of 0, so this is fairly accurate.
right now the api is returning
"value_per_mh_24h": "0.00576"
but my actual calculations for btc/mhash/day is roughly .0064 and .0063 across 2 different rigs
I've also noticed we've been in a decline in profits for a few hours

In the meantime, I do have one request. Would it be possible for the api page:
http://coinshift.com/api/stats/performance/ to also include total payouts in btc? I'm not looking for a "for the day" total, I'm just looking for a "since the beginning" or "from this day forward". Essentially something that will not/never be set back to 0.
I'm writing some scripts to pull out pool vs rig performance, so it would be helpful if there was a way to determine much btc was paid out in total.
as it stands now, I can tell how much MY last payment(s) were (all time payouts on miner page, payout_sum on api page), but I have no idea how much in total was paid out to the pool. As far as I can tell the "Current Pool Balance" from the stats Page/value_24h from the api will get zeroed out every time there is a payout.
