Phoenix estimates the stale shares ratio, so it's not accurate. As you know, what's accurate is the pool. 1 1/2 day mining at anorak tech, no stale at all.
I've just had a look at the Anorak pool some interesting facts as shown on their pool page (correct as at 15.46 UTC)
Miners Online : 155
Pool hashrate 36.23GH
