Not sure what is happening but i seem to have an issue with your pool. I have mined on OzCoin and CoinOTron and everything is good when I started mining here yesterday during the DDOS attacks I was getting such a large number of (unknown-work) shares that CGMiner kept killing the pool and going to my backup. My stales are showing between 20 -30% here. Ihave not changed any of the settings for my cards from when I mine on CoinOTron.

We are definitely still under attack.
If the pattern from last time holds, we'll be under attack until the next difficulty change.
Yeh i also have stales at around 20%.
Is the attack still happening or is the anti DDoS seeing me as a bad boy?
I think it's that there are still enough packets making it through the DDoS filter to hammer the server. Thus the server response is slower than usual, thus the stales.
Sorry, I know it sucks.
