Hi Paul - thanks for providing that link. To clarify, this comes from Ezra's Book of Reasons, not from the Book of Nativities as previously stated by dragonqueen (and the Portuguese blog). Being able to see this quote in context clears the matter up for me; I assumed that the opening post was suggesting that Ezra advocated that adjustment in his general technique, but we can see that he was explaining the calculation made by Indian astrologers.

Cheers
Deb
