Optimum settings

Not sure what my best settings should be. I have two systems going, one doing socks and the other web and connect. I am looking for Google passed proxies for both systems. Both systems initially show a really nice number of Google passed initially, but after a day or so they are basically down to no Google proxies. I know I've got something set up wrong because if I launch on a new machine they come back. Somehow my settings are killing my scrape. Direction on the right settings would be incredibly appreciated.

Thanks
