Hi GS ji,
I will put hre few cents of my understanding here.True it never matters to me whether astrology is Science or not.
Though we can have bigger discussion over it but it wont be useful for anyone of us

.
Though I wont say in india we believe out of tradition of belief but I will just talk about myself..I am very big skeptic and
I started studying this science(rather Palmistry was my starting point) to understand it and then criticise it coz it is the
EASIEST TASK to criticise anything without knowing it like people started criticising "STEPHEN HAWKINS" theory which
does not agree with existence of electrons and protons in nature but he end up shuting them up with his experiment and his book.
(but lets not go there

)
After studying and learning it i relaise it does work though there were flaws but that was not coz astrology as a subject was wrong
or right but coz we MAY have interpretted it wrongly.
You could not find much data on vedic astrology coz of few reasons.One of them is u didnt pay for them
First of all let me tell you KN Rao ji has biggest collection of charts in the world at personal level and his all deductions are based on
his self study and now days study of his own students on these charts which is growing.
There are few articles by Rohiniranajan ji(I remember 2 of them right now which is on retrograde planets and on Kuja Dosha) whcih based on statistics.
There are books by KN Rao jia and his students on working of different dasa systems and working out of marriage and children based on analysis of charts.
There is site online I think its name is "databank" or something like this(u can gogle them) which again is a paid site from whre u can details of
different celebrities whom we know very well and thus can reach to detail of their personal life achevements applying different dasa systems and so on...
Maximum studies which are done is astrology are mainly restricted to astrologer bcoz of few reasons coz pf PARAMPARA system which exist in india.
Secondly , coz they just wana to pass it to RIGHT person. and reason for this is that in india astrology is treated much more piously then western astrolog in west.It is called DIVINE SCIENCE in india and is said to be worse when get into wrong hands
Thirdly,and one of the major reason is that these astrologers are too old or rigid to access computer or internet thus and still are computer illeterate thus coz put their believes and research online for public where as in west astrologers are much more open to computers and also coz computers are easily accessible.So their research is quite restricted.
U can yourself see that in india computers got common among puclic only after 2000 and inter sarted becoming part of urban culture after that but still it is not the case in rural india where great astrologer still exist
If you read KN Rao ji's chara dasa you will hear name "VEMURI SHASTRI" who he says to be teacher whom he never met and who lived in villages of Andra Pradesh
Hope you got my point.
Regards,
Raman
