Anybody getting a grip load of stale shares? I'm at 1.4% stale shares with around 6000 shares submitted.

I switch to btcmine last night when Deepbit was down, but I switched back this morning when I discovered that I had ~155 stale shares after 3700 submitted (4.1%). So far I have 2 stale shares after about 1100 submitted on Deepbit. I use the guiminer.
