I have both some extremely obvious false negative (garbage content, title which is obviously spam, phishing related address) and a lot of false positive including some which hard extremely hard to understand (daily email with always the same title and from the same address - one randomly ends up in the spam folder). At this point, I think Google is just intentionally sabotaging Gmail.
