Which is what I believe happened. The largest proportion of blocks went to miners on the same physical network as the server. Those of us in other continents didn't even get a look in. By the time we submitted out work it was stale.
It also depends on some sheer dumb luck I think? I've got more than 200ms to the io.btcguild server and less hashrate pointed at it than you did... but based on what you had posted, I think I got a few times more i0coins than you before the stales started going down from the new difficulties
yes I got about 9 coins from btc guild.. it didn't seem right at all which is why I changed to http://i0.digbtc.net/
but their page seems down now for some reason
