Anecdata II: I get about 1,500 spams a day to my Google-managed email address, and have found a worrying number of emails in my spam folder. It works really well for you, sadly less well for me :-/
Sorry, but just to be sure - am I getting it right, those emails were false-positives
Yup. For the most part, ones that I'm fine with - e.g. order confirmations from stores - but I've found the odd one in there from someone the first time they email me, most frustrating.
On the other hand, I once nearly missed out on a fun blind date after my initial email was helpfully filtered by Hotmail into the girl-in-question's spam folder. And it didn't even mention Viagra!
