This is speculation, but depending on the configurations it's also possible that Urchin is more aggressively dropping hits from spiders, at the same time that more spiders are becoming JS-aware and thus increasing GA numbers (unrealistically). There are a lot of other possibilities, but that's one thing I'd been pondering recently based on some similar observations. -Brian
