http://www.thespiritscience.net/forum/viewtopic.php?t=1154&p=1154I met my Brother in law and explained to him the issue.
He told me there is exclusively one instance where you can have an exact and errorless assesment for the ptolemaic horoscope, and that's artificial fecondation, where the lab technician puts in contact the male and female cells. This way the time of Conception is imposed.
Otherwise, even with complete medical records, the error is a 2-3 days at best, even when the exact time of mating is known and it is known that it led to Conception, the spermatozoa have a survival time of a few days and the exact time of a succesfull meeting and fusion of the two germinal cells is unknown.
Now this may mean that the part relative to the slower planets (longer orbital times) may still be pretty accurte whereas the faster planet may be unreliable. Also, based on an estimate of the uncertainty of Conception time it would be possible to determine which are the planets and other factor we cannot use with reliability in the ptolemaic horoscope. I think with a few tests you can have an idea about which part of the horoscope can be used.
Also, I don't know if there have been specific studies but now it would be possible to study comparatively the difference between a ptolemaic and a genetliac horoscope in persons born out of artificial Conception, where the time of Conception is exact. So we'd have accuracy in both Conception and Birth times and the differences in the horoscopes would be due only to the methods.
I do not know how much time you spent on astrology but you would not be able to set up a chart with the house system we use today unless you new the time of birth within a half hour. Otherwise you would have to use rectification. I still have an interest in the conception chart but no way of really knowing the time for such a chart. Perhaps such a chart would reveal the physical features of an individual since they are developing in the womb. I am not sure how you mean the astral influences. Some explaining would help.
In doing transits it is evident to me that there is a lot of help understanding events in our life with the birth chart. I do not remember ever hearing anything said discrediting it but rather that the conception chart was more reliable. We must remember that there are also hoary charts so every moment is significant in some way with some being more than others. Your brothers's explanation is purely from a biological testimony;There are other methods but are they reliable? Perhaps I too will someday be able to see sparks in the heavens coming to earth when the soul enters this dimension....must be something!

i pulled this from the internet. Since our Guru Sri Yukteswar used the idea of the conception chart, I am still very interested in this method and how it can be ascertained other than intuitively.
Sorry I can't help you steve, I used to have an interest into astrology many many years ago, when there were no softwares and the hand calcuations took a lot of time, I remember Conception astrology was discussed and some people discarded the idea, retorting that the time of Birth was the one where the individual became really exposed to the astral influence. Maybe the reasoning was a way to go around the almost insormountable difficulties you are hinting at.
Hermes trismegistus is known as a medieval alchemist and the Arabs philosophers and alchemists are from the middle ages s well (dark ages) but probably the idea is an elaboration from the knowledge of higher lost civilizations.
I don't know if today it' s possible to reach an accurate estimate of the time of Conception, I'll ask my Brother in law who is a gynecologist and made thousands of ecographies to pregnant women, I'll get back on this ASAP
