I hope you don't mind me saying that I don't think any type of astrology can be claimed as "more accurate". Astrology is all about how the person whom the message is for reads into the 'prediction'. Therefore I'd argue any astrology can be "accurate" if you read into it in a different way.
That being said, I hope you wouldn't mind if I say that I don't think any kind of astrology can be ACCURATE (let alone "future-telling" for lack of a better phrase).
And for you Kennin, is this what you're looking for?
